I have a result now .....for my problem:
The bot run in a vm (vmware 10.0.1).
Diablo is installed at my main system and linked via networkpath (Z:\) to the vm.
After first start of diablo...the launcher installed basic battle.net start at vm.
Diablo work fine.....
But for some reason it look like the bot is missing a file.
I just copy the diablo folder to my vm and start diablo direct with "-w -launch" and now the bot work.
It doesn't matter if the db folder is at main or vm....only diablo must be copied to a regulary drive from the vm.
maybe someone help this.
