Summary

When attempting to scan a document using any Laserfiche scanning product, the following error is displayed:

The RPC Server is Unavailable

In most cases, this error occurs directly after selecting a scan source and causes the entire program to close.

Cause

An anti-virus program with "real-time protection" is blocking the program from working. For example, if you are running Trend Micro, the Real-time Protection feature causes this error.

Resolution 1

Add the following executables to your anti-virus' exception list:

• LFScan.exe
• BPsession.exe
• BPOmniOCR81.exe

In addition, if you are using:

• Scan Connect then add Scanconnect.exe
• Universal Capture then add FileScan.exe
• Twain then add LFTwain.exe
• Kofax then add LFKofax.exe

Resolution 2

Disable the anti-virus software's "real-time protection" feature.
