We have Visio 2007 packaged as a virtual app, and Office 2007 as physical. If a user attempts to embed an excel spreadsheet into a visio drawing, or attempts to open an embedded excel spreadsheet in a visio drawing, they receive an error which states "Not enough memory to run Microsoft Office Excel. Please close other applications and try again." I have reproduced this on other Windows XP boxes with Office 2007 installed physically/Visio 2007 installed virtually. I've googled, but this is evidently not something that has been reported with these sets of circumstances, so I thought that I would ask here. Thanks for your time.
