I just put an X to the name of my old V4 folders and installed the new V4.2.

These new installers are crap, they don't have a browser. So you have to type your path in or do what I did. I ran the developer .exe and used it's browser to find the path and then copied it. Quit the install and then ran the V4.2 .exe and pasted the proper path. installed fine then and all the other new .exe used the same path.

Unfortunatly your screwed if you want a different path.

Other than that, it all seems to work fine. The morph brush issue is fixed. The male morphs work , though I don't have much use for them. The transform dials are still hidden, to bad, I had hoped they would have fixed that.
