Summary0002293: MSI installer hoses Path environment variable in 2.30.1.
DescriptionThere's already been a report of the installer wiping out Path. I've found that the problem is a little more complicated, which may be why not everybody is reproducing it (if you don't look closely, you won't see what's happening). Rather than simply overwriting Path, the MSI installer seems to be removing _part_ of the existing Path. In my case, I had:

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\totalcmd;I:\EmEditor;I:\PellesC\Bin;I:\LilyPond\usr\bin;I:\LAME;I:\Csound\bin;I:\SBCL\;I:\sox;I:\VstPlugins\Unusual\Studio Units;I:\GTK2-Runtime\bin

After installing Graphviz, this became:


Looks like it's killing everything after the _first_ app-specific entry (in this case, everything after C:\totalcmd). Obviously, Graphviz (which rocks) isn't going to win any friends if it mysteriously breaks all sorts of other software when it's installed! Hence the high priority.
Steps To ReproduceInstall on Windows using the version 2.30.1 MSI installer, while having a Path environment variable with several app-specific folders in it (obviously, you should save your Path variable before trying this!).

As of 2.31, the msi installer does not touch any system files. Users running graphviz from the dos shell will have to set the PATH variable manually.
