Error message

TWAIN error TWERR_OPEN_DSM

Solution

Before performing the steps below, try to remove the TWAIN device and uninstall its drivers from your computer. If this does not resolve the issue, complete the following steps.

  1. Navigate to C:\Windows\Twain_32.
  2. Rename any files that are present by adding .old after the existing extension.

    If the file is in use, your IT professional will need to release the lock on the file so that it can be renamed.

When the files have been renamed, FileCabinet CS should open.

Reinstall the scanner drivers that you uninstalled, or deleted. We recommend that you download the scanner drivers directly from the manufacturer's support site. For more information about scanner compatibility with FileCabinet CS, see Selecting a scanner for use with the CS Professional Suite.
