doing an upgrade from 4.3 to 4.5, W2003 Enterprise SP2, installed MAS90, won't let me install PU2. Tried launching MAS and getting No Valid Activation Found. Executed $actpvx.bat, executed pvxcom.exe from common components, nothing works. Tried reinstalling, same thing. installing now to my local to copy activate.pvx over to see if that helps. Any ideas?
