I cant start server 3.11.0 (CPU does not have POPCNT)

Some corrections, with 3.10.2 either 32 or 64 will work fine without POPCNT support. 3.11.0 32 & 64 bit versions require POPCNT. Based on beta release notes: Starting with 3.12.0 32 bit will again not require POPCNT, but the 64 bit will continue to required POPCNT and should have better error messages to report this. If running on a VPS you may have to run the 32 bit even with a 64 bit processor that by spec does support POPCNT due to the virtualization layer removing some instructions from the CPU the VM sees.

Also looking like POPCNT may only be required for Windows 64, if I’m reading that right.
