Log from dotnetfx3.exe

In 1.7.17 the .NET 3.0 installer starts to install, encounters an error, and
rolls back the installation.

Disclaimer: I ran the regression test using winetricks dotnet30 for
convenience, but I also tested manually running dotnetfx3.exe, and the same
problem occurs.

Regression test results:

The patch does not revert cleanly.

The attached log is from running dotnetfx3.exe manually (.NET 2.0 already
installed to the wineprefix).
