Launching characters in wrong order breaks Inner Space
I've encountered a major issue while trialing ISBoxer. I'm running a druid/hunter combo in WoW Classic and use the quick setup wizard in ISBoxer to setup my team and I specify that launcher should be used when choosing the character set. Now this works fine most of the time, however the other day I managed to log in druid on slot1 and hunter on slot2 when it should be the other way around. I got the error message ingame and closed everything and launched again, except now when launching the character set the following popups happen:
#1 Starting Battle.net
#2 Updating Blizzard Agent (hangs on around 60-70% until #3 pops)
#3 An error message appears saying "We're having trouble starting Battle.net. Please try again. If the problem persists, try restarting your computer."
Restarting computer does not help, reinstalling ISBoxer/Inner Space does not help, creating new character sets that launches client instead does not help, reinstalling WoW does not help and deleting various Blizzard folders mentioned in threads that resolve the given launcher error in %ProgramData% does not help. I can still launch battle.net from the same .exe specified in Inner Space config and play the game normally. Now, for some reason completely reinstalling NVIDIA driver solved the issue that time, but alas, today I managed to launch the same account twice and immediately got the same error happening and reinstalling NVIDIA driver does not help this time around.
I'm 100% blown away by ISBoxer itself, so I really hope to find a solid fix for this, but as of now I cannot purchase a licence when the trial ends on thursday.
Does anyone have any idea where the problem might be?
To re-iterate; WoW launcher works fine when I launch it myself, the problem only happens when Inner Space tries launching the game and I've tried reinstalling ISBoxer/Inner Space.
