I originally started way back with PowerProducer 2 and subsequent upgrades then on to PowerDirector 5 and subsequent upgrades to PowerDirector 9. Once I got to 9, I started having all sorts of problems and getting the message 'PowerDirector has stopped working' and yes, I had all the latest drivers etc.. At this point I decided to rebuild my PC (Windows 7 64bit, etc.) - at the time it was just one year old and plenty capable of handling the software. When I tried to reinstall PD9 I got the message I needed to install version 8, this occurred several times going backwards each time with lots of uninstalls and 'start again' etc. I eventually got there after a lot of work but still had problems.
In the end I gave up with PowerDirector for the time being.
Now I am considering PowerDirector 11. Do I really have to go all the way back to 2007 installs first? I am not even sure if I have the old software still available however, I still have the keys.
Seems like a lot of work if I want to install PowerDirector as an upgrade or I have to rebuild my PC (or I purchase a new one).
