windows 11
I have been using Thunderbird on my windows systems for years. For some reason I wanted to install Thunderbird again. I deleted the existing installation with Geek. When trying to install thunderbird again I am given 2 choices.

1) Install as my computer name
2) Administrator.

If choose option # 1 nothing happens.
If I choose option # 2 it asks for administrative password. I do not know my administrative password

If I choose to install as Administrator it installs without a hitch.

In my same desktop I have separate "Windows 11-practice" on dedicated ssd.
I can install windows 11 by just clicking on the thunderbird exe file.

What is the explanation?

Or did you mean you can open Windows by that clicking? Windows already has to be installed and running before Thunderbird can be installed and ran.

I've installed Thunderbird a few times this year without issues but the clients were running with Administrative Rights, no requirement to enter permissions. One installation didn't even have a Microsoft Account, ran as a Local Account with admin rights. A Standard User can't do as much to the computer.
