Mathcad Prime 3.0 won't re-install
Yesterday I had Mathcad Prime 3.0 installed and running. Today I had to restore Windows 7, so I tried to install Prime again after downloading pim_installmgr_mathcad.exe again, but it won't re-install -only the quality agent. 

PTC Mathcad and Mathcad PDSi viewable won't re-install.
