I downloaded a PSP program, which uses an ActiveX control (COMDLG32.OCX). It was working fine earlier, then I ran one of those registry cleaners which probably messed it up. I sorted the errors, but I get an "You do not have an appropriate license to use this functionality" error when opening the program. The program wasn't installed, its just a stand alone program. I looked on Google, but nothing helped. I tried re-registering the .OCX but nothing worked. What can I do?

Did you try deleting then downloading again?

Yup, but when I Googled the problem, ActiveX was the known cause.

Certain ActiveX objects (even general ones) come only with certain programs you install in Windows. But not all of these ActiveX objects can be used by 3rd party developpers to make tools with them.

It is only when you install a legit development packet, for example Visual Studio, Visual Basic, etc, that many ActiveX objects will recieve a design-time license so they can be used by 3rd party developpers (aka: you).

Now, if for any reason these ActiveX objects were installed after you have installed a development packet, the ActiveX objects will not recieve their design-time license update. If they were already installed on the system prior to installing the development packet, then they will recieve their design-time license.

ADDED: If registry keys got messed up or you accidently removed the licenses in the registry, you need to reinstall such development packages.

Note that such development license keys are illegal to redistribute! They come only with packages such as Visual Studio, Visual Basic, etc,
