This doesn't fix it. I'm not certain what does. I have some machines running fine with 401 and others that still crash even though they have identical setups. Memclean doesn't seem to be the issue. The crashing also seems sporadic. I have one that has been running fine for the last week. I thought it may have been the visual c++ redistributables, but they're all running the same versions now.
It is not yet fixed. Error spontaneous, so until I found the cause of its origin...
