This looks like a crystal reports error. Has Crystal Reports been installed on the Win 7 PC?

It is a Crystal Reports error.

Crystal does NOT need to be installed on the client PC.  You do need to install the run times.

What version of Crystal are you using?

How are you connecting to the database?
You probably need to install the 32-bit database drivers and create the connection using those.

If it is an ODBC connection the 32-bit ODBC connections are not created through the control panel but by using the ODBC 32 app in SysWow64

Have you tried running it in compatibility mode

Right click on the EXE or the shortcut and click properties. Then check the compatibility mode check box and select Windows XP SP3

CR 8.5 is quite old (think Win 97 and 2K)

I assume this is a thick client application.  CR8.5 was never really net aware.

Are you using ODBC to connect to the database?

What database are you using?

There was an update, service pack, for CR8.5 specifically for SQL Server 2K.  I susect without that you may be in trouble

I thought I had a copy but i can't find it.
