running anki without installing it has been discussed many times - in this forum and other places. This is not officially supported but there are multiple reports that it works for users. You could start with a search of this forum for "portable windows" or "Running from Flash drive". I guess it's better to get the answers in context than just a few lines here. This has also been discussed multiple times in the anki subreddit.
I did not try yet: I'm teacher and the new school year is beginning. If
there were a straight forward solution I would have use it with wy student.
There I will have to seek and test, so I plan to do it on my next holiday.
Thank's a lot for the link. Starting from there, the IT could find an
package designed for opsi software installation that is official and
allowed to be installed. So I did not try the instruction in the manual.
I propose to leave your post here to inform others.
