It’s usually a registry key, especially if there’s 2 of them missing.

 

And for XP

 

1.Remove the Upperfilters and Lowerfilters values completely from the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
NOTE: If you are getting a code 39 message, it may be that additional third-party filter drivers were added to UpperFilters and LowerFilters values in addition to Adaptec filter drivers. In that case, you may try to remove the non-Adaptec filter drivers first, leaving the Easy Creator filters in place to see if the Code 39 goes away. If you still receive an error code 39, 32, or 31 message, remove the Upperfilters and Lowerfilters values completely in the preceding key.

2. Restart your computer.
