I can log into any account after pressing Play, but the game always crashes after pressing Play if I try logging into any other account.
The issue was duplicated on two different PCs, both running Windows 7.
The issue does not exist on Windows 10.
Launcher was reinstalled/repaired, Installation was verified/repaired, game was fully uninstalled and reinstalled. Issue persists.
The issue is not specific to any account. After successfully logging into one account, I could no longer log into any subsequent accounts after clicking Play.
The following solution worked for me.
"Here are two workarounds that should help players on Windows 7 who encounter the C1/C7 error.
- Workaround 1: disable desktop composition in the compatibility settings
- Workaround 2: Start swtor.exe and launcher.exe as admin w/ compatibility for XP SP3"
After logging in once, I restored the settings to normal. But then this switched which account was "stuck". Now I can log into Account 2 but not Account 1. Admin w/XP SP3 Compatibility seemed to be the fix for me.
