I am running:
windows 10 64bit
FSX-SE
FSUIPC 4955c
WideFS
I have not had a successful flight in the middle east where I was doing a couple flights. PF3 crashes once I get airborne. The first was OOSA-OYSN. The second was OYSN-HSSS. And I cannot send the error report through PF3 because it keeps timing out. So, I just manually emailed my last one with attachment.
I run PF3 on a second computer via WideFS and it also is on a windows 10 OS, but 32 bit.
