Q10100 - ERRMSG: Runtime error 430: Class does not support Automation

Summary
When attempting to create a mail merge, Word opens and you recieve an error 'Runtime erorr 430: Class does not support Automation or doesn't support expected interface.

More Information
This error may occur when software attempts to access a database file by referencing libraries that are a different version than those installed on the computer.

After reinstall the Commence program or applying a patch file, it is possible to receive this error message.  Use the following steps to manually register the letters.dll :

  1. Use Explorer to locate a file called regsvr32.exe,
  2. Create a shortcut to the file & place it on the desktop. 
  3. Locate the Commence program directory.
  4. Drag the letters.dll file from the program directory to the regsrv32.exe shortcut on the desktop. 

You should receive a message stating the file has been successfully register.  Now attempt to create your mail merge again.

Advanced
If the error continues:

  1. Using Windows Explorer, locate the CMCMERGE.DOT file in the Word Startup directory.  Right-click and select open.
  2. Open the VBA Editor using the ALT+F11 shortcut or the Tools - Macros - Visual Basic Editor command.
  3. Select Tools -References and locate the reference for Letters.dll.  De-select or remove the checkbox.  Select OK to close the dialog box.
  4. Select the Debug - Compile Project command.  We expect this will error out. Click OK to the message box.
  5. Use the Tools-References command and locate the reference for Letters.dll.  If there are multiple listings, verify the path to LETTERS.DLL is the proper one for your current Commence program directory. 
  6. Select Letters.dll so that a checkbox appears.
  7. Click OK to close the dialog box and select the Debug-Compile Project command. We expect no error should occur.
  8. Select File-Save in the VBA editor.  Select File - Close and Return to Word.
  9. Select File-Save in Word to save the CMCMERGE.DOT file.

If more than one PC is receiving this error, the modified cmcmerge.dot file may be copied to the remaining workstations
