Help to upload an OLB file

Hi everybody,

I've developed a tool in Excel that mainly uses two libraries (to be exact an OLB file and an OCX file) but I'm having problems when using it in Excel 2007 or Excel 2010.

To avoid that, I want to upload the needed files depending on the office version I use.

So, the problem is that I can detect the version but I'm having problems to upload the OLB and OCX files.

Can somebody help me on that?

Thanks in advance.
