PGHook.dll error on windows 7

[bilalhussain]

Hi,

I want to use Virtual Box on my Office PC running windows (to run Juniper router in GNS3).
After getting it installed, I tried to run it but got this error

C:\PROGRAM~\....\PGHOOK.dll is either not designed to run on Windows or it contains an error. Try installing the program again using original installation media or contact your system administrator or the software vendor for support.

I got Virtual Box re-installed but same error. I don't have admin rights as I am not System Administrator.

Is this error due to some 'admin rights' issue or is Anti Virus program stopping it from running. The Anti virus program I have on my PC is 'Trend Micro Scan'.

Please help.

Thanks.
