This is basically just to Steffen but i think NSIS 2 is good enough despite officially only being beta. How about upgrading?
I guess you're talking about the new NSIS GUI.Looks like a complete rewrite of the installer is necessary for this, my first attempt to upgrade the existing file failed. At least the created installer is not crashing any more.
I would like to wait a little bit more before upgrading. Steffen
