I Emailed Tech Support But Never Heard Back!

Business hours are 8am to 6 pm Pacific Time M-F. We usually respond within 30 minutes during that time frame. Between 6-10 pm emails are monitored but not as frequently. If you haven’t heard from us within a reasonable amount of time, then consider the following:

  • Our response ended up in your spam folder – check that first.
  • Your internet service provider may have flagged us as spam.

Here’s a couple of things you can do:

  • Email us again and try using a different return email if you have one.
  • Provide a phone number where you can be reached. We do our tech support by email, but if you’re not getting our responses we’ll call if necessary to try to get the lines of communication working.

Mac Users - Read before you update to Sonoma--

Q. Is CheckBuilderPro compatible with the "Sonoma" Mac OS?
A. Version 3.5.4 (released in early September) and newer are compatible. Previous versions will crash on Sonoma. If you're running a previous version, update *before* installing Sonoma - click the "Updates" icon in the toolbar. Otherwise contact us for a download link.

Misc Issues

Q. When I try to open the software I get a notice, "An error occurred while initializing the application [unable to load external Preferences]."
Update to version 3.5.4 or newer. Otherwise, make sure CheckBuilderPro3 is set to open using "Rosetta":

1) Locate the "CheckBuilderPro3" app in your "Applications" folder
2) Click *one* time on the app
3) From the "File" menu at the top of the screen select "Get Info"
4) On the "General" tab make sure the checkmark "Open using Rosetta" is checked

To make sure Rosetta is enabled, turn your Mac off and then back on again, then try to open the CheckBuilderPro3 app. If it prompts you to enable "Rosetta," you need to do so.

See this post in Apple support for more info:

Q. Trying to update to the latest version fails - what do I do?
We've had a small percentage of users who cannot update. It goes through the process of downloading but then fails. We are actively investigating. Contact us for a link to a new installer to get the latest version. Be sure to include the name and email that your purchase was made with so we can verify you as a customer.

Q. How do I use the backup feature? 
To use the backup feature proceed as follows (version 3.3.1 or newer required):

1) Open Preferences and go to the 4th tab "Backup." There are brief instructions at the top of that screen.
2) Click the "Select Location" button and navigate to a location that you want (do NOT place it inside the same folder as your check storage folder "CheckBuilderPro3 Docs"). If you want to back up to an external drive make sure to attach that first.
3) If you want to automatically run the backup when you *quit* the software, click the checkbox "Auto Backup When Exiting Program."
4) You can manually backup by clicking the "Utilities" icon in the toolbar and selecting "Backup" or by selecting "Backup" from the main File menu.

Q. I got a warning that CheckBuilderPro is not optimized for my Mac - what should I do? 
You're running a really old copy of  CBP and need to upgrade to the CheckBuilderPro version 3. It is a 64-bit app and has lots of new features in addition to its 64 bit compatibility.

Q. Can I use my checks created in version 2 in the new version 3?
A. The older check will not open in version 3 BUT there is a converter that can quickly and easily extract all the data from your version 2 checks (account & routing numbers, logos, check register, fonts, layout, check register data, etc) and then import that into a version 3 check:

1) In CBP3 open the "CBP2 Converter" from the "Utility" icon in the toolbar.

2) If the converter does not find your version 2 checks automatically, locate the "CheckBuilderPro Documents" folder (by default in your Documents folder). Note: The version 3 folder is named "CheckBuilderPro3 Docs" - you don't want that folder for the conversion.

3) Drag and drop the "CheckBuilderPro Documents" folder onto the "Drop Folder Here" button on the converter window.

4) Follow the directions there.

Q. Why am I getting an error message that my check storage is not found?
A. The folder where your checks are stored has a slightly different name depending on which version of CheckBuilderPro you have:

CheckBuilderPro 3.x: “CheckBuilderPro3 Docs”
CheckBuilderPro 2.x: “CheckBuilderPro Documents”

You could try a search for “CheckBuilderPro” – exact spelling (no spaces in “CheckBuilderPro”) and restrict your search to "Folder." If found, click and drag the folder onto the Preferences window onto the 3rd tab (Document Location) where it says “Current Storage Folder Location.” This will point the program to this folder where your checks are stored.

If you want to move your check storage folder, use the “Set/Move” popup menu below the box that lists the current location. There are presets for DropBox and Google Drive  (if installed) and your Documents folder. To select a different location, choose “Select other” and designate your location.

Q. Can I re-download the software? The link I have has expired.
A. All of our download links expire after 48 hours, but if you’re a registered user in good standing, just contact us and we’ll send you a new link to re-download the software. Be sure to include the name and email you used when you made your purchase so we can verify you as a customer. If there has been a paid upgrade that you have not purchased we can send you a link for the latest version in the series you did purchase.

Q. I reinstalled the software and now it's asking for a "validation key."
A. If you can't find your validation key, contact us with the name or email that was used when you purchased, so we can look up your validation key. Just a first name or a different email will not work!

Q. Does CheckBuilderPro network with other installations of CheckBuilderPro on the same network?
A. No it does not have any built-in networking capability. You can set up the check storage location in Dropbox or similar cloud sync services. All computers you'd want to have access would need to have Dropbox installed and be logged in to the *same* account. Contact us for instructions on set-up.

Q. Where can I see the checks that I've written?
A. With a check open, simply click the "Check Register" button right under the bank routing and account numbers.

Printing a Check

Q. How do I print a blank check without a payee and amount?
A. With your check open, just click the "Blank Checks" button just under the bank routing and account numbers on the very left side of the check. Verify the starting check number and enter the number of pages. If you're printing a multiple checks per page format, you also have the option to print just 1 check. Then click "Print."

The "Write Checks" screen is only for those wanting to print completed checks with payee, amount, etc., not blank checks.

Q. Can I print on pre-printed checks?

A. Possibly. Your checks would need to be in sheet form (8.5x11 in the tall orientation) and be Quickbooks/Quicken compatible. Checks in other formats (checks removed from a checkbook, "notebook-style" checks, etc) are not supported. We would recommend you try our free demo to make sure this will work for you.

Q. How do I reprint a check that I've already printed?
A. There are 2 possible ways to reprint a check:
1) If the check is still listed in the "Checks To Print" window then click 1 time in the space before the payee name so that there is a check mark visible. Then print as usual. Or--
2) Open the check register and click 1 time on the check you want to reprint. Then click the "Edit" icon at the top of the register window and select "Reprint."). This will add the check back to the "Checks to Print" window where you can print as usual.

In both cases the software will reprint with the same check number (even though the print window will show the next number in your sequence). Also, after printing you will get a warning that the check was not posted to the register. This is as expected as the check has already been posted.

Q. The routing and account number are printing in the wrong font/I’m getting an error that the MICR font is not loading What should I do?
Assuming that you’re running version 2.1 build 6 or newer, in “Preferences” at the bottom is a check box labeled, “Use MICR Symbols.” Click this so that there is a check mark. Then close and reopen your check.

The root of the problem is most likely a corrupted font cache on your computer, which you may want to fix, but this will get you around the problem. Note: This solution will slow printing time slightly.

Q. The fonts on my check look OK on the screen, but when I print on Mac my check they look really bad – what can I do?
A. If you're running on Mac, in all likelihood you have a corrupted font cache. The easiest way to clear and rebuild this cache is to restart your computer in “safe mode” then restart normally:

1. Quit all open programs.
2. Select “Restart…” from the Apple menu.
3. Immediately after you hear the startup tone, hold down the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
5. After the computer has booted up, do a normal restart.

*Please note: Starting in Safe Mode will clear the font cache. Just be aware that if you have created font sets with the Apple Font Book program or disabled any fonts, these settings will be lost and will have to be redone.

Q. My check looks fine on the screen but some of the text areas don’t print – what is the problem?
A.  If you're running on Mac, more then likely you have a font conflict. Clear the font cache (see previous question for procedure). Next, in your Application folder there should be a program called Font Book – it comes on all Macs. Open it up, and:

1. Select all your fonts and from the File menu select “Validate Fonts.”
2. Select all your fonts and from the Edit menu, select “Resolve Duplicates.”
3. Reboot your computer and try printing again. If it still isn’t working right, contact us for further help.

Another thing to try is to go to the web site for your printer manufacturer and see if for your specific printer model there is a: 1) a printer software update; 2) a firmware update.

Q. My checks won't scan at the bank – what’s wrong?

A. Most banks these days have optical scanners which do not require special MICR toner/ink. But the old-style magnetic scanners are still in use by some. The official bank recommendation is that the MICR line (routing and account numbers) be printed in magnetic MICR ink/toner. A check printed with normal ink/toner is not readable by magnetic scanners. MICR toner is available for some printers. Advantage Laser Products sells MICR toner for some HP, Canon and Troy printers. Or you could Google your printer model + "MICR."

Q. My graphics are printing with poor quality – what’s wrong?
A. The preferred format for graphics is JPEG or PNG - these will give the best quality. Also, the original size of the image should be roughly twice what you'll want. Then use the sizing control slider to size.

Q. My printer is cutting off the image at the top/bottom of the page – what can I do to prevent this?
A. All printers have a margin area where it cannot print. Try moving your check image on the page by using the controls on the “Layout” panel of the editing window. If the bottom margin is the problem, you could try creating a custom page size (like 8.5 x 11.5) (On Mac go to File menu > Page Setup…) to trick your printer into giving you more room. This may require using the manual feed tray on some printers.

Q. Can I enter checks with different dates?
A. Yes. Open Preferences and go to the second tab “Checks & Deposits.” About half way down is a setting for “Set Check Date When Writing Check or Printing Check.” Set that to “Write” and when you enter a check to print it will pre-date it with the date you’ve selected. Otherwise if you set the preference to “Print” it will print the same date for all checks based on the date you’ve selected.

Q. Can I print a check without a date?
A. No, you cannot print a completed check (with payee and amount) without a date. You can print a blank check and fill it in manually. Then enter that check into the register manually by clicking the "Enter Transaction" button at the top of the register window. Make sure to designate it as a debit.


Q. How do I update/upgrade my copy of CheckBuilderPro?
A. With CheckBuilderPro open, in the toolbar click the “Updates” icon. If there is an update, you can choose to download and install it. After the update is finished it will automatically relaunch the program. If you have any trouble, contact us for a new link to download.


Q. I’m getting an error about “write privileges” on my Mac – what do I do?
A. Try repairing permissions with the Disk Utility program. If that doesn’t work, check permissions on your check storage folder:
If you started with a version older than 2.1, look here:
Users > (your user name) > Library > Application Support > com.knappstersolutions.checkbuilderpro

If you started with version 2.1 or newer, look here:
Users > (your user name) > Documents > CheckBuilderPro Documents

Click the folder once, “Get Info” from the File menu. Permissions should be:
-your user name- (Me) – “Read & Write”

Editing a Check

Q. I would like to have a blank line in my address – how do I get that?
A. In the editor, enter a non-printing character like a space in the line where you want a blank. Otherwise the program will strip your address of any blank lines before it enters it into the check.

Q. My bank doesn’t use a fractional routing number. How do I handle this in CheckBuilderPro?
A. With version 2.1 or newer, go to the bank #s tab and click the “Hide FR” checkbox – that’s it.

Q. I live in Canada and I can’t get the software to format the bank routing number correctly – what should I do?
A. Our software only works with U.S. banks, which is why we place “For U.S. Banks Only” on almost every page of our web site! We have some Canadian customers using our business-style templates. The only real issue is the date format but they've told us that they've been able to use that (their assessment not ours). Our personal-style will definitely not work - the MICR line does not configure to Canadian specs.
