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

"There has been no mapping between account name and security-id."

I never got the promt after typing: takeown /f /t /g everyone:F, I only got the message above.

This is exactly the same problem as you had before. It seems you need to familiarise yourself with the Swedish account and group names, in this case the group "everyone". This script will tell you what they are. You must save it on your desktop as "Names.vbs". The .vbs extension is essential!

I did that, at nr 4 I got the message: 

"There has been no mapping between account name and security-id."

I never got the promt after typing: takeown /f /t /g everyone:F, I only got the message above.

Then nothing, no change still can't install new programs on the computer.

I did not really understand what you suggested that I do in your last message, besides confirming the group name. So I only confirmed it nothing more.

I get the impression that you never followed my suggestion. Here it is again:

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.
