Hi Haitham:

What Windows OS are you running on?

This error looks like there may be some problem with the Forte installation or an incompatibility with the OS. 

Another possibility is that Forte was not installed with administrator privileges.  The latter will prevent Forte from accessing certain system files, like .dlls

I would consider completely removing Forte from the machine and reinstalling it.

Best Regards,
