Error loading DLL Unknown Reason error loading VRS Scan Source

Question / Problem:

When loading the scanner VRS source in Kofax Capture, the following error message appears:

Error loading DLL - Unknown reason

Is there a fix for this issue?

Answer / Solution:

After clicking OK on the first error, the following error message may also appear:

Unable to initialize: <Scanner_Name> with VRS with AIPE Error In Loading DLL

Check the following possibilities:

1. Cable is properly connected.
2. Scanner has power.
3. Accelerator board is set up properly.
4. The correct scanner is connected.

This issue can be caused by a missing or corrupted libxml2.dll file. It has been observed that copying the libxml2.dll file from the ImgCtrls\Bin folder to the Windows\System32 folder resolves this issue.

Folder paths are as follows:

• 64-bit Windows
  Copy FROM:
  C:\Program Files (x86)\Kofax\Capture\ImgCtls\Bin
  Copy TO:
  C:\Windows\System32

Note: If the error still occurs, add a copy of the DLL to the following directory: C:\Windows\SysWOW64

• 32-bit Windows
  Copy FROM:
  C:\Program Files\Kofax\Capture\ImgCtls\Bin
  Copy TO:
  C:\Windows\System32

If the above steps do not resolve the issue, please run the System File Checker Tool provided by Microsoft to attempt to repair any missing or corrupted system files
