I'm guessing you have an Acer laptop? There's a problem with objectdock and the dataprotection stuff preloaded on Acer laptops.
What I did for Acer laptops was to disable those.
1. Run as admin, you'll need to change some files
2. Go to:
My Computer--> C: --> Acer --> Empowering Technology --> eDataSecurity --> x64
Go into both folders and find the PSDProtect.dll file, rename them noPSDProtect.dll and that should solve you problems.
If you're not running an acer laptop then please post the rest of your details and there will be someone else to help you out.
