To answer your questions:

What steps have you taken to verify that this error message reflects reality?

I think there is enoug disk and memory. Refer my previous answer.

I don't believe the message reflects reality. But I don't know why I would get a spurious message if the script deoes the right thing.

Re: What steps have you taken to remedy this error condition?

I googled the message and did not find a similar experience. The error is reported in different circumstances. Seems to indicate that others have been able to install Win32::OLE under cygwin.

I used Win32::OLE under XP, Excel 200? and cygwin. Installed without issues. So maybe there is something about Win 7 or Excel 2010

I tried the script in the debugger. I posted the Trace. I also checked variable values. They look normal, although I have no definitive idea what the values should be and the perl constructs used are beyond my expeience.

I have no idea how to progress this further.
