This can mean to some files or registry entries. I find some registry tools to other be at the source of this one but check in your EVENT VIEWER for finer details then we can change the ownership or file attributes to let this install.
I have a PC running Windows XP Pro SP2. For the past couple of months, I haven't been able to get patches installed. I use HFNetChkPro at my work for patch management and deployment. This has been failing for no apparent reason. When I try to install them via Windows/Microsoft Update, they too fail with no reason given. As a last resort, I downloaded the patches manually to the machine and tried to execute them one at a time. The patch begins to extract then throws up an error that says Access Denied. When I hit okay, another error pops up saying Installation did not complete. Then it's over with. I noticed that the directory it says it's extracting to never gets created. I have checked the permissions of the c: drive to those of several other machines and they all appear to be set the same way. The machine in question is a member of a 2003 active directory and the policy has been refreshed to ensure that nothing in that area has been hosed.
If anybody can shed any light on this it would be greatly appreciated. Shavlik and Micorsoft were both called and neither one of them were any help.
