If you are constantly getting the error message “error opening group file” and MultiCHAX cannot print, your printer driver may not be available or compatible.


Please follow these instructions:

  1. Go to C:\MultiCHX\temp
  2. Delete all the files from Temp Folder
  3. Temp folder should always remain empty
  4. Open MultiCHAX
  5. Click on Change Printer
  6. Select your MICR Printer


NOTE: Please make sure that when selecting a printer within MultiCHAX, DO NOT SELECT the MultiCHAX Virtual Printer. Only select the MultiCHAX Virtual Printer in your accounting software.
