DLL's not removed from Windows\System folder

[Nick]

Please help...
On installation, I am placing a couple of dlls in the Windows\System folder. When I uninstall, everything is removed except for the dlls in the System folder. Why???

Thanks for help.

Which DLLs are those? Your own or some Windows DLLs? If it is the second case, maybe some other applications are still using/needing them...

Thank you for your help.
These are my own dlls. I am installing, which places the dlls in the system folder, and immediatley remove without even starting the application.

I made a dummy file "test.dll" and also placed that in the system folder. Interestingly, this one is removed correctly.

The dll's are not opened at removal time. I can erase them manually. Actually no other application makes use of those dlls. Does installer check the registry for some references of any other application? Where can I look that up in case?

Strange... Any other ideas???

Thanks again!

If this works witn another dll, then there is a problem with the original dll on your test machine. Maybe after the first install you never uninstalled it?

You should search the registry (with regedit) for the DLL name and component GUID.
