I am currently running Windows 7 64 bit.
I can only open certain files such as Internet Explorer 64 bit, but not the 32 bit version.
All other borwsers, game applications and programs, besides Ventrilo, which is also in the C:Program Files Folder do not open. I can also get Regedit to work, which is also an exe, but outside of the Program files folder.
CMD also opens just fine Symtoms:
I click on the application icon in the containing folder, and the program does not open.
No new process appears in the task manager and I see a momentary spike in CPU usage.
If I right click to run as Administrator In the task Manager I see the dllhost.exe appear twice for about 3 seconds and then it dissappears and the application does not load.
The application never appears in the Applications Tab of the Task Manager.
Attempting to run any installations including system updates also result in failure.
Right Clicking on the application Icon to attempt a Scan will result in the scan not running due to the scanning software not loading. Attempts to resolve:
I have Merged .exe and .dll associations,
I have ran system restore,
I have attempted to run applications in Safe mode and applications do not load.
Moved Files form other folders into the C:Program files This did not work either.
Ran Applications as differnt versions of windows for campatablity.
Ran Applications as Administrator.
Any Help would be appreciated.
