--- Comment #1 from Dan Kegel dank@kegel.com 2012-07-10 12:17:53 CDT --- I can't quite reproduce that problem, but Mathcad 15 requires .net 3.5sp1 to install. It doesn't put up that error unless you do 'winetricks dotnet20' before installing. Sadly, 'winetricks dotnet35sp1' doesn't work yet.
Anyway, unless you have .net 3.5 sp1 installed, this bug is probably invalid.
