Hi there,

We are trying to use lfscanning as usual, but for some reason today is not working, we lfscan opens it shows a message saying "

Laserfiche Scanning:
Exception has been thrown by the target of an invocation.

COMException:
Failure to retrieve COM class factory component with CLSID {3DF14013-6449-49F8-A3E2-7FB27A184B96} due to the following error: 800702e4. "

Does anyone had this problem before??

There is a known issue with the hotfix where in some cases it replaces 32-bit files with their 64-bit versions and causing LFScanning's scan engines to stop loading.

Delete the following files, then repair the installation to get back the original ones:

C:\Program Files (x86)\Common Files\Laserfiche\9.1\BPImageWrapper91.dll
C:\Program Files (x86)\Common Files\Laserfiche\Batch Processor\BPInterfacesClient.dll
C:\Program Files (x86)\Common Files\Laserfiche\Batch Processor\BPObjectsClient91.dll
C:\Program Files (x86)\Common Files\Laserfiche\Batch Processor\BPOCRClientWrapper90.dll
C:\Program Files (x86)\Common Files\Laserfiche\Batch Processor\BPPageFixClient91.dll

Do you have Kofax installed? You should be able to click OK on the error message and then pick a different scan engine.
