I am having this binding issue:

LOG: This bind starts in default load context.
LOG: No application configuration file found.
LOG: Using machine configuration file from
C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\co nfig\machine.config.
LOG: Post-policy reference: Oracle.DataAccess, Version=2.102.2.20,
Culture=neutral, PublicKeyToken=89b483f429c47342
LOG: Attempting download of new URL
file:///C:/Asta/bin/Oracle.DataAccess.DLL.
WRN: Comparing the assembly name resulted in the mismatch: Revision Number
ERR: Failed to complete setup of assembly (hr = 0x80131040). Probing
terminated.

Where exactly is the mismatch. The same DLL and EXE using it appear to work
fine on another PC.

thanks for your help,
