@letyo: yes, I tried something similar, but for me the point of quick create is to get the latest version of the cms. As that did not work, I settled for manual download and creating a new folder in /www . Laragon automatically sets up virtual hosts and ssl when i restart the server, so it is pretty convenient.
@thomasdominic : sorry, i did not find a solution on the machine with issues, but i've had it working on another machine, but with conciderable delay (several minutes) in the extraction process, see details below.
@leokhoa : FYI: i'm using laragon as a portable installation, moving it around on an external ssd. I just tried it on a surface pro 4 with the same version of Laragon as before and now it worked! But it was slow. Download and unpacking went fine and quick in just a few seconds, then it was stuck at 0% extraction for about two minutes, jumped to 33% for about two minutes, same with 67%, then to 100%. About 6 minutes total for extraction. Anyway, no big deal-breaker for me
