You guys are good! I did set min_dynamic_shared_memory to 2 GB in the new config, which didn't exist on 11. I can set it to 0 and give it a try on Tuesday. Does 2 GB seem overkill? We have plenty of memory to go by.
dynamic_shared_memory_type = windows # the default is the first option
# supported by the operating system:
# posix
# sysv
# windows
# mmap
# (change requires restart)
min_dynamic_shared_memory = 2GB # (change requires restart)
Thanks!
Maxime

I've tried on master:
echo min_dynamic_shared_memory = 10MB >c:\temp\extra.config set TEMP_CONFIG=c:\temp\extra.config vcregress check
and got:
...
Installation complete.

With your patch applied, `vcregress check` passes just fine.
Best regards,
