So, I tried to install Build 9926 in a VMware virtual machine. It didn’t work out very well.
As it turns out, if the x64 build is installed in VMware using any date/time/currency format other than English (US), the install will stay blocked for a long time on this screen:
By “blocked”, I mean “the spinner spins, the CPU is maxed out, and no HDD or network activity occurs”. By “long time”, I mean “Discourse’s InfiniSpinner found a worthwhile competitor”. I mean, in my case, between 8 and 12 hours.
If any of these criteria is not met, the installation will work in a much more reasonable amount of time (~20 minutes).
I… I got nothing.
