Trouble passing data from Windows apps to Office:mac 2011

Running Parallels 6.0.12090 / Windows 7 on an iMac with OS X 10.6.8. Installed Office:mac 2011. Running a Windows app called PG Calc, there is an option to Edit the current information in Word. When using this option, Word:mac opens, but it's a blank document. The same happens if I use the option to Send to Excel - Excel:mac opens but it's a blank spreadsheet.

If I attempt to open a Word document from Windows, Word:mac opens the document just fine.

We also saw the same issue with QuickBooks 2011 for Windows, it did not "see" Excel on the Mac side, so exporting did not work. Solution was to install a copy of Excel 2007 on that system. I'd rather not have to do the same thing with Word on this system, otherwise what was the point of installing Office:mac?

I checked various support articles, but they mostly seemed to apply to Windows XP - Windows 7 doesn't give a lot of options for setting up file associations.

Thanks for any suggestions.
