.Net Framework problem. Can't update or install

I think I might have run the dism program.
Not sure.

A window popped up for a second and closed.
Tried to install 4.7.2 and got a fatal error

The DISM should be installed update. You can access it by opening an elevated command prompt window and then typing DISM /Online /Cleanup-Image.

If the computer cannot find DISM then check your Updates for KB3006137 . If needed you can download and install that update from here: fix windows update errors by using the dism or system update readiness

How do I o[en an elevated command prompt?

Thanks for your patience

Sorry to be so dumb.
I downloaded from the link and installed it but I don't know where to look for it or how to open an elevated command prompt

I just ran the DISM /online /cleanup-image

Got error 87
Attaching logs

Thanks for your patient help

Hi Larry,

Dism doesnt play well with W7.

Well, installed the system update readiness tool and then tried to install 4.7.2 and it failed

Hi Larry,

copy/paste the results.

its in C >> Windows >> Logs >> CBS ... SURT.

might also be handy to run sfc /scannow.

Hello larryfoster, sorry to leave you high and dry - I'd been might busy today.

Anyway, regarding posts #25 and #24. Looking at this one explains the other. Error 87 is because DISM /online /cleanup-image was not run from an elevated command prompt.

An elevated command prompt is also called an administrators command prompt. You get this by running the command as an administrator.

To run cmd.exe as an administrator, open Start Menu, in search box, type cmd. When cmd shows in search results, select it with right-mouse click, and then select Run as administrator from the dropdown list. Input admin password if necessary, when prompted.

When the administrators command prompt window has opened, re-type DISM /Online /Cleanup-Image and run the command again. See what results you get.
