I patch my GroupWise messenger environment from 1.0.4 to 1.0.5 and we have the client to update on everybody's workstation at login.

I got a large number of clients that received this message.

CRC error: The file C:\Novell\Messenger\nmclen.chm doesn't match the file in the setup's .cab file.
The medium from which you are running the setup may be corrupted; contact your software vendor.

The client install gives tree responses. Ignore Cancel, or Retry. If they cancel or retry they ruin IM that is on here workstation and we now have to uninstall and reinstall. If they Ignore and allow the install to complete. messenger works fine.

Has any one seen this problem.
