Installation completes, but shows an error (mpm.exe)

[GrayFace]

• I have read and acknowledged this HOWTO article:
  Submitting a MiKTeX problem report

System:
Win 7 x64, UAC turned off.

Steps:

1. Renamed the basic-miktex-21.6-x64.exe from https://miktex.org/download into miktex-portable.exe
2. Ran it selecting c:\Programs\MikTex\ folder, "A4" and "Yes" to automatic package installation.
3. After all files are extracted the error described below is shown.
4. Despite that, the installation seems to function correctly: I've updated with mpm.exe, successfully compiled a LaTeX document, all packages required by it got installed.

The operation could not be completed for the following reason: 

The executed process did not succeed.

Details: fileName="c:\Programs\MikTex\texmfs\install\miktex\bin\x64\mpm.exe", exitCode="1"

[edocevoli]

The installation should succeed if you do not run the installer with elevated privileges.

[GrayFace]

I'm not running it with elevated privileges. If failing when UAC is turned off is intended, then it has to to so the moment the installer is run with a clear messsage. Current behavior is obviously a bug.

[edocevoli]

I'm not running it with elevated privileges.

The report says something else:

RootPrivileges: yes

[GrayFace]

I'm not running it with elevated privileges.

The report says something else:

RootPrivileges: yes

Like I said, I run it normally. UAC is disabled (because it doesn't protect from anything), so everything runs with "root privileges".

[GrayFace]

You need to reopen the issue.

[edocevoli]

basic-miktex-21.8-x64.exe should fix the issue. This version will be available tomorrow.
