Add/Remove program problem
I'm trying to upgrade a very old application and I'm using NSIS to create my installer. The problem I'm currently having is that after I run my installer, the old version of the program still appears in the Add/Remove programs of Control Panel.

I don't have access to the Windows Registry of my computer, because of security reasons, the company where I work won't allow it. So I can't get the uninstall information. I think the old app was installed using Installshield but I can't find the ODEUNST.LOG file.

Is there another way of getting the uninstall information from the computer?
And if so, how can I remove the entry using NSIS script?

Thanks !

You don't have read access to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall? Or is regedit.exe locked down?

i would say first if you can read write to the registry via nsis try to delete the uninstall key might be under the product name or the vendors name ect.
if its regedit you cant run get a copy of some other registry program or find a copy
of bart pe or any pe bootable cd that will let you access the registry files on the root c: drive and edit them. (not responsible if you get fired :) )
