it was my friend who installed it, yesterday I asked him to install an antivirus instead of Malwarebytes temporarily. until Malwarebytes runs normally (by the way sorry if I reply too long, because I'm still a student)

mbst-grab-results.zip

ok, no problem when launching malwarebytes. but still can't connect to server, still "unable contact to license server" and "unable contact to update server"

ummm, what should I do?

Fixlog.txt

OK, now what should I do?

I can't turn off "Always register Malwarebytes in the Windows Security Center" because it's only for premium. malwarebytes works but can't connect "update server" and "license server" or in other words, things that need connection to server don't work

I can't turn it off, because it's only for premium. My premium trial period expired a few days ago

after reinstalling the message "Malwarebytes fo Windows installation has been canceled" appears even though I didn't cancel the installation mbst-grab-results.zip

the trial period is over, it's been a long time since I used malwarebytes on windows. this problem happened since last week

mbst-grab-results.zip I have a problem about "unable to contact license server" I have tried all suggestions in this forum but it doesn't solve the problem
