QuickBooks 2008 Remote Applciation Publishing & Windows Server 2008 STD x64

Quickbooks 2008 Premeir Edition is installed and working on Windows

It appears to work well using Microsfot's new published application feature with one exception;

When we attempt to print to the "QuickBooks PDF Printer", or to email from within QB (which appears to use the QuickBooks PDF Printer as well) we get the following error;

"Quickbooks cannot connect to your server because part of your company data is currently in use".

I realize x64 is not supported, however publishing QB as an app is very convenient and everything else seems to work without issue.

This seems like a simple QuickBooks PDF Printer (Amyuni PDF Creator) x32/x64 print driver issue.

I have researched this group and Amyuni's support site and tried several suggestions and upates, etc., all without success.

Any suggestions appreciated.

Thanks.
