VB6 Error - Cannot load .ocx File

com vb6 registry ocx

I have been trying to load a OCX file into one of my VB6 projects for most of the day today. I've tried checking the COM registration in the registry the best that I know how, and have attempted several times using REGSVR32 on the file to no avail. All I keep getting from VB6 when I try to load the component (Under Project --> Components) is 'FilePath\FileName.ocx' could not be loaded. Has anyone else seen this before, and if so, any ideas how to fix it?

Just a couple of tips to help isolate the problem....

Look at the control with OleView

Examine the name: if it is one of the reserved words such as 'Menu', vb6 will fail to load it. (Although vb6 will happily let you create (and use) one with a bad name until it is saved and reloaded)

Examine the interface: does it describe the functionality? You may have a damaged or unlicensed ocx.

Attempt to load it with the ActiveX Control Test Container... If you can, the problem is with VB6 and not the ocx.
