Cannot install VSIX with VS2015

[zpqrtbnk]

I have installed VS2015 RTM. Whenever I double-click Zbu.ModelsBuilder VSIX file, nothing happens. An exception is logged in the event logged about some UnauthorizedAccess exception being thrown when trying to open the VSIX installer log.

Manually launch the VSIXinstaller.exe from \Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE - same issue unless I'm administrator and then it works. From the help menu that opens, we see that VSIX installer wants to create log files in %TEMP%.

Which is \Users\Stéphane... for me... Oh... now there's a \Users\St%C3%A9phane directory too, that was created when VS2015 was installed, and sure enough... the install logs are there. Give my user full permission on that directory...

... and now when I double-click the VSIX file, it works. So the issue is with VSIX installer that has an issue understanding the accent in my user directory. Damn damn damn.

VSIX installer does something similar to new Uri(Path.GetTempPath()) and that creates an invalid path.
Write to: Path.Combine(Path.GetTempPath(), "test.txt") => works.
Write to: new Uri(new Uri(Path.GetTempPath()), "test.txt").AbsolutePath => fails.

OK, that has to be a bug within the VSIX installer. What's strange is that the code does not seem to have change. Reported to MS...
