I had the same problem, I had to disable the antivirus protection Avira (for the protection of real-time registry) and reinstalled MBARW and then it worked. Obviously I do not know if this only applies in my case. Best wishes

Many thanks temp_9999 for your replay, also it happens to me (in both April and May) that the installation stops responding when it reaches the 59% loaded. I think we will not be the only ones with this problem and I'm curious to see that there will be developments with respect to the possible solutions by good Malwarebytes programmers. regards Alex

By chance I discovered that if I uninstall Antiramsonware can do the update cumulatative of April and May for Windows 10 pro 64 bit. Otherwise leaving it installed, the cumulative update fail! With reboot loop and continuous rollback. I hope to be helpful to other forum friends. Thank you and continue with this good work !!
