I am attempting to virtualize Outlook 2007 with ZAV 7.3 I use the Office 2007customization tool to set up my MSP and then use ZAV for the rest on a clean virtual PC. the virtual app works fine on clean PCs, but on PCs with Microsoft Office 2003 installed on them it doesn't. When launching the virtual app on these PCs, it keeps saying 'Please wait while Windows configures Microsoft Office Professional Edition 2003' and then looks for the PRO11.MSI. After about htting cancel 3 to 4 times, it finally loads.

If the app is working withing a sandbox, why is it trying to configure Office 2003? In my Outlook MSP I disabled all of the shared tools and even set it to not uninstall previous versions of Office, but that hasn't helped.

Thanks in advance,
