Parallel Error on Install "Problem ID 352 Unable to load Parallels Drivers"

Everything has worked great in the past and I had a HD failure on the iMac. Fixed everything up physically and now Im trying to reinstall Parallel 7 (yes old but it worked perfectly for the older programs). Now I keep getting this error? Running same OS 10.9.5 so it should work... Anyone have any ideas.

 

Hi Family1,

Parallels Desktop 7 for Mac is an old version (End of Life) product. It is not compatible with Mac OS X 10.9.5
