So did I understand you correctly:
* You tried to upgrade from 3.2.0.53 to 3.2.0.63 and this resulted a installer crash?

Yes exactly! (And I closed Skype before installing the latest version)

We have released yesterday new 3.2 beta version it has many changes in installer and it should also fix your problem.

Yes, installing the .82 version was fine and no crash

Though memory consumption is still too high - hope to see something in this reasonable improving.
