Hello,
all my WU crashed after a few seconds (5-10). On all my systems (Win7 x64, GTX1060-1070Ti).
C++ correctly installed.
Any idea about this "unknow error" ?
Best regards

Stderr output

I don't know about an unknown error, but "app exit status: 0xc0000135" is very much a known error: you're missing a Microsoft runtime file.

See message 57353.

Later in that thread, they say they've fixed this problem, but evidently they haven't.

Hello Richard,
UIO checked again. I have the dll.
C++ 2012, 2015 and 2015-19 installed.

I suspended a WU after 2 second and looked at stderr.txt
At start a message "memory leaks"
But this one dispeared in final stderr.txt !

Strange the question mark after "data":

Also strange another wu

It looks like everyone has the same problem

Thanks
