Error installing MiKTeX Portable using installer basic-miktex-2.9.7152-x64.exe

[wtrmute]

Hello,

I've downloaded the installer for MiKTeX v 2.9.7152 and renamed it to miktex-portable.exe in order to install the distribution as portable. However, the intallation failed; the log (attached) says:

 initexmf --rmfndb --admin --log- file=C:\Users\tiago.rodrigues\MikTeX\texmfs/install\miktex/config\uninst.log --disable-installer --verbose:
 Option --admin only makes sense for a shared MiKTeX setup.

 Sorry, but "MiKTeX Configuration Utility" did not succeed for the following reason:

Here's the result of running initexmf.exe --report using Git Bash:

Apparently, the installer emits the --admin flag for portable installs because I am a local administrator and initexmf complains about it.

I thank you in advance for your attention.

• I have read the MiKTeX Contributing Guidelines

Have you tried to run the installer un-elevated?

Normally, a local administrator gains root permissions only on request (elevation). It seems that you have configured your Windows system to bypass the elevation prompt.

Yes, Windows is configured to bypass the elevation prompt. I recommend that MiKTeX be allowed to install without an error under such conditions.
