AutoUpdate.exe Error

We run Vantage 8.03 and are on a Linux Server.

When I do a Client Install, after the program completes its load and
installs the desktop icons, I run an icon to complete the install.
The AutoUpdate tries to run and I get an Error. The error is as

Strong name validation failed for assembly 'C:\clinet803
\Client\AutoUpdate.exe'. The file may have been tampered with or it
was partially signed but not fully signed with the correct private key.

Has anyone seen this error before. I have loaded 30 other clients
machines successfully before this. This just happened on the last two
installs for some reason.

Please let me know if anyone has run into this problem and what the
fix might be.

Thanks - Les Jaynes
