I remotely updated ESS to the 4.2 and it locked up during the install - registry key failure on update. The PC had to be hard reset, eset is there but corrupted to start kernel. Every attempt to uninstall or reinstall fails with registry permissions. I have logged in with admin with service perms and I can not remove these keys for the services or the hklm software eset The installer errors on scheduler key first then eventually can not ignore past the service key. had someone reboot the PC in safemode, tried running the esetuninstaller.exe it detects the install but it fails on removing the keys also, permissions. I have tried taking ownership on all keys starting from the subkeys, no access. I removed all the common locations of exe files. I have created a new user with admin priv, still no access. I tried the MS install cleaner, doesn't see eset installed. I cleaned out the temp files and cached msi. I have tried several tools that try to reset perms on the keys. There has to be another way to get this uninstalled without me going up there with a boot CD to manually remove the registry key from offline editor. Is there a system dll loaded up protecting the entries even in safe mode? All the keys are visible, just no type of changes are allowed.
