I upgraded a Windows 7 computer to the Client 2 SP1 IR4 client due to a continuing problem with random invalid handles and unable to write errors on IR3. After rebooting, an application that runs off the server now won't run and Windows 7 says it's not a valid win32 application. None of the machines running the IR3 have the problem. I'm leaving the IR 4 on for now to see if the file write problems will go away, but I really kind of need to have that other app running at some point!

I have completely uninstalled and deleted the previous version of the Novell Client from the computer including the registry and reinstalled and still get the same message. Don't know if there is an option to change that might affect this or not.
