Few weeks ago I installed the release version of office 2007 enterprise. Few days ago I tried to install, German's language pack, MS Project and Visio. During installation procedure following error appears:
Setup is unable to proceed due to the following error(s):
The 2007 Microsoft Office system does not support upgrading from a prerelease version of the 2007 Microsoft Office system. You must first uninstall any prerelease versions of the 2007 Microsoft Office system products and associated technologies.
Correct the issue(s) listed above and re-run setup.
To solve the problem I uninstalled the "AddIn Support for Infopath BETA". The interesting thing is that I do not remember when and for what reason I installed this component
