.NET2 generates error-boxes of same type upon uninstalling

0.4.8-RC-18-g64dcc95 gcc dbg

-Install .NET2 from rapps (not SP2, the older one)
-restart (like the setup requests)
-uninstall .NET2

The setup will present several "Error 0" messageboxes. net2uninstall.png
0.4.8-RC-18-g64dcc95__NET2uninstall.log
Hammering Cancel multiple times and the uninstall will finally report success.
It's gone from the rapps list then.

Sidenote: Its ASPNET_STATE service will still be visible in servman then (but I did not double-check that detail yet on a 2k3sp2 uninstall)
