I have an older Citrix/Terminal server running Windows 2000 SP4 with Microsoft Office XP (2002) SP3 that has been running without problem for several years. Over the weekend I applied Microsoft's latest security patches (released in April 2010) and now the Office application will not open documents created in Office 2007.
Here is the actual message that pops up:
This is a pre-release version of the Compatibility Pack and can open pre-release Office 2007 files only. Do you want to check for a newer version of the Compatibility Pack?
We have never used a beta version of any program on this server and I know it was working correctly last week; therefore, I am working on the assumtion that one of the several patches Microsoft put out in April (Windows 2000, Office XP and Office 2007 patches) has caused the Compatibility Pack to "think" it is a pre-release version. I have already tried removing the original Compatibility Pack, rebooting and then reinstalling the latest Compatibility Pack from Microsoft's web site (1/6/2010 version). No change. I also tried the Office 2007 converter administrative template with the group policy editor suggested by Microsoft. No change. I can not do the manual registry hack they suggest for the HKeyCurrentUser policy setting as this is a Citrix server so every user on the system, of course, has their own HKCU settings. Has anyone else run into this and if so are there any other fixes I can try?
