I have the same problem. CUDA 11.8 could not be installed with the HAIBAL Installer. I then installed CUDA 11.8 myself, and copied the contents of the CUDNN bin folder to the CUDA bin folder.
Then I started the HAIBAL installer again. The dialog window opens again and displays the installed CUDA version.
If I press the button “Fetch” I get an error message
Then I installed “graiphic_lib_haibal_deep_learning-126.96.36.199.vip” with VIPM.
As with Vlady, the examples are not executable for me either.
