I’ve just updated to the version they just released this month as an extension from the one released in October and the app will no longer open. Anything I can try? ETA: So I have some absolutely fantastic news... the new launcher as well as TSO application are officially working now with OpenGL as well as with my program I use with it!!!!! (Knock on wood!) After uninstalling (updating windows required me to as the older would no longer open). I decided to take one last effort at getting it working before rolling back windows by disabling all of my antivirus software as well as closing Afterburner and Rivatuner and when I reinstalled it worked!!! Absolutely could not believe it was that.... my anti malware programs works fine with it but AB and RSS will not. They worked fine with the old launcher though. No big deal at all! Just ecstatic it’s working. I also noticed when I reinstalled with antivirus turned off it installed all of the downloads needed through the launcher in the same folder in program files whereas before when I installed and it wouldn’t launch with OpenGL it weirdly split files between program files and program files x86 with a folder entitled The Sims Online. So I think that may have had something to do with it. I am so very grateful to everyone on here for being so kind and helpful. I’m so glad it’s working!
