Permissions problem after upgrading to Windows 7 from Vista

  1. I upgraded a machine running Vista to Windows 7. Now when I try to update some programs, like Adobe reader, the update fails because the installer does not have permission to access certain folders.

    I have checked the permissions for these folders and everyone has access to them and can modify them, so I am not sure why the installers don't.

    Any thoughts?

    You could try Foxit reader

    the problem is not limited to adobe - now I can't even add Microsoft Security Essentials.

    What happened it looks like is that the owner of the c:windows folder was TrustedInstaller and I wasn't able to give everyone full control as I thought I had. So I took ownership of that folder. Now I think that removing TrustedInstaller is causing the problems so I will try keeping myself as the owner but adding TrustedInstaller as having full control permissions.

    Try going to -user accounts,change user accounts-and set to "never notify".

    thanks. I will try.

    But now I find that I can't add TrustedInstaller.

    Sorry,,,I have discovered that the suggestion above isn't likely to work.

    You could look into the "TakeOwnership" program. Perhaps, it could help.

    I have that program and it worked for all folders except the one's that were owned by TrustedInstaller.

    I have been researching this and it is a problem for many windows 7 users. I wouldn't have messed with the permissions at all since it is not my computer, but adobe and other programs wouldn't install due to permissions issues.
