Error 5 when trying to install programs

Question

First off I have read several posts on here and tried every solution I could find to no avail. 

When I try to install new programs on this computer running Windows 7 I get error 5, "Setup was unable to create the directory" C:/user/[username]/appdata/local/temp/...

I have all permissions to do this, even right clicking and trying to run the installer as admin does not work.

I have run system file checker, performance troubleshooter, I have updated windows and nothing works.

What can I do to fix this?

Answer 1

Yes that's right "Administratörer", so what do I do now?

Well, I do not really know what you were doing when you ran into the "Administratörer" problem.

Answer 2

Answer 3

I followed your instructions and at the last one I got this message: (translated from Swedish) "There has been no mapping between account name and security-id."

The group name "Administrators" is localised. In your case it could be "Administratorer". You can find out for sure by type this command at the Command Prompt:

net localgroup

Answer 4

So I finally got access to the computer again and I did as you said. First, pressing Ctrl+Shift+Enter did as I saw, nothing, and I could not left-click on anything, cmd just started, but at the top of it did say that it was running as administrator.

I followed your instructions and at the last one I got this message: (translated from Swedish) "There has been no mapping between account name and security-id."

What now?

Answer 5

It seems contradictory that you are allowed to create a file in the temp directory by manual means but not while installing new software. Maybe the following procedure will resolve the problem:

1. Reboot into Safe Mode.
2. Click the Start globe and type this:  cmd.exe
3. Press Ctrl+Shift+Enter, then left-click Run as administrator. You will get a black screen.
4. Type the following commands exactly and press Enter after each:

cd  /d  "%temp%"

cd  ..

(yes, that's two full stops!)

takeown  /f  temp  /r

cacls  temp  /c  /t  /g  everyone:F

(answer Yes when prompted) 5. Reboot normally and check if this solves the problem. If not, check on a different machine if the problem occurs there too.
