Today I installed Office 2007 in CrossOver 11.3.1 for Mac (using the .tie file). I installed it into a new, separate WinXP bottle. The installation went well and after the installation all the programs were visible in the bottle (ok, to be fair I don’t know which ones were supposed to be there but none of the main programs were missing).
However, the programs did not show up in the Programs menu and double clicking them in the Bottle Manager did nothing.
Searching for answers on the web in general and on CodeWeavers support pages gave no solution.
SOLUTION
I then tried to install Office again from the same DVD, this time a different installer came up, as it recognized that Office was already installed (good sign).
After having run the "Repair" option (which did take some time), suddenly all the programs were added to their respective folders in Finder and in the Programs menu.
So, if you run into something similar – installing Office a second time and running "Repair" might do the trick.
