Any idea how to resolve this issue ?
openhab> C:\openhab\userdata\bin\openHAB-service.bat install
Error executing command: bad unicode
Hi and welcome,
To be Honest i have no Idea about using Openhab on Windows. So i might not be of much Help 
Anyways:
-
Does Openhab run if you Start it as described here? Windows | openHAB
-
Did you run the command as adminsitrator?
-
(out of having no other idea): Maybe some files are corrupted? Maybe donwnload again and start over?
What System are you trying to use Openhab on?
Greetings
Manuel
seems to point to a problem due to using a non ASCII character like German Umlauts somewhere.
Does the Windows eventviewer provide more information about the problem/error ?
