I have been watching this thread with interest. Carl has certainly been giving you valuable advice. I note in your most recent post though that you have three anti-virus programs running, and that could be causing huge problems for your computer. I suggest you Google the SystemCare software. It seems to be listed as malware itself.
Running more than one a/v app will usually result in a very, very sluggish computer as the a/vprograms struggle with each other. Try uninstalling all but one of your a/v programs and I would recommend that System Care be one of the removed programs, based on what my Google search revealed.
Then uninstall your PD. Once that is uninstalled, and I hope that you have kept your installer files, then disable your remaining a/v app long enough to install the PD files. I suspect that your computer might be able to launch PD after that. Some a/v apps stop PD from installing correctly.
Hope this helps. Have a great day.
