Then I think I've made a mess of my installation setup because I did not realize this.

For my older version, I installed activeX controls (like DBI's ctTree and RichTx32.ocx) into System32 under Windows. These were registered by the install program

When I came out with a new version, I changed the application folder name and got the install program to put the activeX controls into the same folder as the application. These were also registered by the install program.

I had assumed that the registry would know which controls to use for each application.

But if there is only one entry in the registry, then I guess the second install did not actually register the controls, as they were already registered!

This issue has arisen because a user has just uninstalled the older version, and the new version now gives an OLE error.

Note: I thought it would be a good idea to avoid placing the controls into System.


So what are my options? Should I create a new install program that puts everything into System?
Or should I write a registration file which the user can run if they have OLE problems. This file will I guess contain:

regsvr32.exe "c:\ABC8\Richtx32.ocx"
regsvr32.exe "c:\ABC8\ctTree.ocx"


Any advice?

If you have multiple version of an ActiveX/COM server installed, than you will have multiple entries in the registry under HKEY_CLASSES_ROOT in the form < Program >.< Component >.< Version >. They point to the CLSID of the component. You may have multiple entries that all points to the same CLSID.
