I installed a piece of software that created an entry in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\DNI_DNEMP\0000 (it was Cisco VPN Client). This software is causing windows to Blue Screen when i run it so i need to reinstall it FYI, I am running Vista Ultimate (i upgraded from vista home premium which apparently results in something different than just installing Ultimate from the ground up). When i try to uninstall the vpn client from the "add remove programs" (or equivalent) utility the uninstall fails. So i have manually deleted the files used by this app, at least those that i have access to. Next i tried deleting all the registry entries for the Cisco VPN Client which worked until i got to "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\DNI_DNEMP\0000". Apparently in Vista, even as admin, i dont have the right to modify anything (including permissions) under that Enum key. I have read posts on this forum that say i need a "system integrity level" account to make permissions changes in that key. I have read posts talking about how to do this in code but I need to do it as an administrator (minimal coding). Is this possible or do i need to completely reinstall windows because i don't have this permission?
Thanks for the post. I did tried that and it did not work (i would receive no errors but when i viewed the permissions again my change would not have been made). I was part of the administrators group so i don't understand why that didnt work especially because i could change other keys (anything above "Enum") without problems. I ended up reinstalling Vista and on my current install that key is owned by "Administrators" already.
