Cant open MBAM, reinstalled, now cant connect server and token error in Malwarebytes for Windows Support Forum Posted 4 hours ago · Edited 4 hours ago by Porthos 24 minutes ago, Tguy27 said: Nothing, again unable to contact license server and installation token not found. I suggest turning off fast startup in Windows. Then restart. https://www.tenforums.com/tutorials/4189-turn-off-fast-startup-windows-10-a.html ESET could be the issue. I would also recommend creating exclusions between Malwarebytes and Your AV to help prevent any possible conflicts or performance issues. Please add the items listed in this support article to Your AV 's allow list(s)/trust list(s)/exclusion list(s) particularly for any of its real-time protection components and likewise add Your AV 's program folder(s) (likely located under C:\Program Files and/or C:\Program Files (x86)) to Malwarebytes' Allow List using the method described under the Allow a file or folder section of this support article and do the same for its primary data folder which is likely located under C:\ProgramData (you may need to show hidden files and folders to see it).
