cuda simple application working for 32 bit not for 64 bit

Question

My simple cuda helloworld application runs fine when built in 32 bit using visual studio 2015 community on windows 10. However, if I build it in 64 bit, it is not executed

Answer 1

I faced the same issue and opened a bug to nvidia #1855074.

They reproduced it successfully and I'm waiting for update on it.

One thing is sure, it's on their side.

The only workaround I found was to put my card in WDDM mode via nvidia-smi, which broke my taskbar.

I recommend to wait for a fix.
