Cannot install MSE - error 0x80070643

Here's what I think may the critical error...

Code:

It looks as if the permissions on the System32 folder may be screwed.

Please open an Elevated Command Prompt, and run the following commands...

ICACLS C:\Windows
ICACLS C:\Windows\System32
ICACLS C:\Windows\winsxs


Post the results.


Here are some instructions to make life easier :)
1) To open an Elevated Command Prompt Window (the ECP window), click on Start, All Programs, Accessories – then right-click on Command Prompt, and select Run as Administrator. Accept the UAC prompt.
2) To run the commands easier, highlight the block of commands, and right-click on the highlight – select Copy. In the CP Window, click on the black/white icon at top left – select Paste. The commands will run but may not complete the last command, so hit the Enter Key once.
3) To copy the results... click on the Black/White icon in the top left, and select Edit... 'Select All', and hit the Enter key - then use Ctrl+V or r-click+Paste to paste it into your response.

Ooops! - sorry!

back later.

If anyone is interested I finally fixed this. It was a problem with my permissions with my ProgramData folder; I couldn't install MSE, Skype, Microsoft office and other Microsoft software. I ran this command:

Code:

 icacls "c:\ProgramData" /T /C /grant administrators:F

and all the programs can now install fine.

By chance have you installed a anti virus program yet? The reason I ask is many infection can and will change permissions settings.

Your specs.

Hard Drives Samsung 840 EVO 500GB | WD Caviar Blue 500GB
Internet Speed 2.5 Mbps
Antivirus --None--
Browser Google Chrome

Well Malwarebytes does a fine job except it's not a anti virus program it's a anti malware program.
Virus and malware are two different things.

I use MSE along with Malwarebytes Premium.
Only the Premium will monitor your system active.

Can you after the repair install MSE?

After all you started out with this thread title.
