Question / Problem:
Some batches processed through PDF Generator, with PDF Compression enabled, may encounter an 'Unknown Exception' error.
- Not all batches or images may cause the issue to occur;
- The error message is unspecific and is included in the Batch History, as follows:

Is this a known Bug? Is there any FixPack or Workarounds available?

Note: A permanent solution is expected within Kofax Capture 11.0; Service Pack 1; FixPack 1 (KC188.8.131.52).
2. Alternative Workaround(s) to patching the affected machine(s) running PDF Generator are included, below:
A) Roll back the version of the Kofax VirtualReScan software to VRS 184.108.40.206, if it is possible as PDF Compression uses the underlying ImageControls from VRS.
B) Add or modify a tag for the ACConfig.xml to force different PDF Compression engine, if the resulting image quality is acceptable to business:
<PDF_Compression_Settings EnableDLCompression="1" DLCompressionQuality="2" />
Note: Once enabled, the old PDF Compression engine is no longer used, regardless of the settings in the PDF profiles.
