deleting and unregistering an OCX

[MartyMcFly]

I have a problem with an activeX control.
My Uninstaller shall delete and unregister the activeX control that I had installed before.
But how can I be sure that no other software is using the OCX later.

e.g.
This OCX is also included in visual studio.

I install my app(installs and register the OCX), then install visual studio(it registers their OCXs), I uninstall my app(unregister and deletes the OCX).

the visual studio would have problems with the unregistered OCX.

Is there a possibility to check if my app is the only one in the system which uses this ActiveX control.

See section B9 of the documentation. However, the shared DLL registration method of Windows is not always that reliable.
