If I start Ceres (v0.96) in a command line session with PAD I get the following error:

Loaded network weights: 0 10x128 WDL MLH from ./Networks/weights_run2_703810.pb.gz

CUDA driver is installed, and starting by hand in a command line window works without problems.

The error message stats that the cublas64_11.dll file cannot be found. I do not understand the specifics of how PAD works, but I suggest you locate this file and put it somewhere on the system path so it can be found by a program running from any directory. This will hopefully solve the issue.
