I've attempted to install several items in my computer. So far, all have complained about being unable to access a part of the registry. My game, Rome: Total War complains about being unable to write save files to the disk. I'm becoming concerned that some security program is causing problems...or worse...

Any ideas?

Hmmm.... this might be a stupid question, but how much hard disk space is left on your machine?

My system drive is a Seagate, ST3250823A. I bought it new and have had it for about 3 years.

Thanks for the input ^_^.

Hmmmm.. that drive is getting boarderline old. You may want to go to Seagates site and download a hard drive diagnostic tool to check and make sure the drive is working 100%.

I've done the drive test, and everything appears to be working okay.

I have an example of the error messages i get when i'm trying to install programs (SystemMechanic in this case):

"Error writing to registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

RegSetValueEx failed; code 5.
Access is denied"

Thoughts?

Thanks ^_^

You could try giving your profile name full permissions to that particular registry key...that may help.

More info here:

It's a guide for windows 2003 but it's the same principle.

When i try to change the permissions on the key with Regalyzer, i get an error message:

-Could not change key security: Access denied

When i go into permissions in Regedit, the user account that i'm running (Administrator) has Full control and Read marked on the allow list. There is a users called RESTRICTED. This is the only account with only read access and not full control. When i change it to full control, the same access issues occur. Upon restart, the list of "users" in the permissions window has changed. RESTRICTED no longer exists, and now CREATOR OWNER, Power Users, and Users exist. Respectively, they allow none, allow read only, and allow read only.

Thoughts?

Thanks ^_^

You will probably need to take ownership of the key. After clicking permissions, select the Advanced button then the owner tab and then select your name and then put a tick in the box at the bottom then click Apply/OK. Once you have done that, you should be able to edit the permissions but make sure you back up the key before doing that.

Hope that helps :)

There are now several branches of this problem...

One, more registry keys are now being denied editing. This was most notable when i recently installed an updated graphics driver for my video card. Nearly 20 error reports saying that the program could not gain write access to certain keys, CLASSID and Software/CurrentVersion/Run (i think) among them. I've checked them all in regedit. They all have full control permitted.

A game that i recently uninstalled has an empty directory left on my drive. When i go to delete it, an error message appears indicating access denied, that the directory is write protected or being used by another program. When i attempt to install over it, same issue.

Any ideas? I'm going crazy here x_x

I was having issues installing Media Player 11 after running the RegSeeker "repair" program (won't do that again), and the tip on regaining access to Registry keys was exactly what I needed.

Thanks very much.
