Can you post the exact pasman command you are trying to execute?
I have tried to add the instance with the OpenEdge Explorer.
What happens if you copy-paste the below command getting executed and run it in a proenv prompt
D:\fid11_64\dlc\servers\pasoe\bin\tcman.bat create -p 8080 -N ZenPasoe -s "\-1" -P 8443 -m *** -f -Z developer D:\fid11_64\dlcwork\ZenPasoe
I have tried to execute the command in proenv, but no result, nothing happened.
After re-installinging OE with Administrator rights the issue was solved.
I guess it was a security issue..
