I had installed winetricks sometime in the past. How do I verify if it is being seen? 33006 does not seem to have been resolved.
winetricks is a utility containing some tweaks to install common packages from windows in wine. You can not "install" winetricks, you just get it and run it.
In comment 4 of bug 33006 contains the workaround . You need to run the comand:
winetricks dotnet20 dotnet35
on the shell as a requirement to get WindowsXPSP3andnewer__256.exe working.
