Hi,
I just wanted to report a bug happening with the Malwarebytes Support Tool, latest version downloaded from your official link on this page (mb-support-1.8.1.883.exe).
Once launched and clicked yes for admin privilege, it shows "extracting", and upon completion a progression bar with "Getting file information" followed by "Downloading mb-support-1.8.1.883.exe", followed by the previous "extracting"... and so on.
I have reproduced this bug on 2 different computers, both of which have different hardware and are on different networks. The file isn't new (I checked on digital signature) and I have used it successfully in the past. My guess is that the problem comes from your end on the network level. The only way to use the Support Tool is to disable the internet connection and use it offline. If the internet connection is switched on while the Support Tool is currently launched, it still works as well.
Anyway, I was just reporting the bug so that you guys could fix it up and other users wouldn't be stuck as well. As of me I don't have any issue as I was just uninstalling Malwarebytes as my antivirus requires it to be uninstalled (I will of course install Malwarebytes afterward). I'm quite happy with Malwarebytes (I have the Premium + Privacy package) and have the upmost respect for your work.
Have a good one and stay safe.
PS: I have uploaded a video showing what happens, in case that could help
