Invalid DLL Entry Point - How to handle this Error ?

When I try to run a Setup application (The Setup application actually registers the Windows Common Controls and other .ocx in the system such as comctl32.ocx, msflxgrd.ocx and a list of others),
I get the error message "Setup1.exe - Invalid DLL Entry Point".
After this it says it is unable to register all the .ocx , the setup is
supposed to register. The OS is a Windows NT 4.0 Server.
The Setup application is not corrupted. There were no errors during OS installation. How do I resolve this error and proceed with running the setup ?


Kindly let me know the quickest and best way.

what is the program you are trying to install? its an odd problem, have you visited the manufacture website to see if there is an issue with your service pack of nt?

The problem lay in the order of installation of software.
I tried to install Windows NT Option Pack 4.0 after installing
MS Office 97. Later when I tried to install an application which simply registers all the ocx ( which we generally use in any vb/vc application) and MDAC , there must have been a version incompatibility (between what files ??!!) and that is why the ocx refused to get registered and threw up the aforesaid error. When I installed Windows NT Option Pack 4.0 before installing MS office 97 and then installed my application, the error did not occur.

Thanks
