Just a suggestion but have you tried installing by running as administrator and / or running PD13 as administrator ?
Aithough my user has admin rights, Win7 fails to run some bits of sofware, I have to run them as administrator.
Some hang as your description of PD13, does, some fail to open photos.
Win7 seems very fussy about who owns what and the access privilages that are needed.
When I posted my problems on the Forum, I was advised to make another user with admin rights and see if the problems were resoolved. To some extent they were, but I still have to change the exe files on some to run as administrator.

PS I have also found the hard way that SSD drives have a problem sometimes with setting restore points in Win7. They seem to want to do there own thing, and the PC comes to fast braking halt. It maybe worth trying by switching off the Win7 Restore widget / thingy and see what happens ?
There is advice on the web regardind SSDs and the problems with the Win7 Trim command and restore points.
