--- Comment #7 from Ulrich Brammer ubrammer@t-online.de 2012-05-21 15:34:57 CDT --- The confusion with the drives is introduces with the commit:2a59f016dbe716aaefec9ab94d47d7b8172d0b5b Author: Alexandre Julliard
The drives tab looks identical, because I set it identical just before the install. The commit above does also have the effect of no detected drive c: in winecfg. I had to add drive c: before the install.
I install from a copy of the installation CD on my harddrive. I set this path in winecfg just before the install.
I made the bad install with a wine version 1.3.35 just set to the commit above and a good install with the same wine version set to the last commit before. I could not made a good install with the actual version, because the commit from A. Julliard can not cleanly reverted at the actual version.
I made in the mean time a test. I exchanged the different registry keys regarding microsoft office in a bad install to the keys from a good install. The installation turns into a good one.
