Not sure if this problem is unique to the Sims 2 or not, but I use a special injection launcher for it (SimsRPC). Since it fixes one of the largest bugs built into the game, as well as having some other QoL features, I run the game exclusively from this alternate launcher. However, every time I close then reload Launchbox, whether I played the game or not, the Launching .exe is reset to the default rather than remaining on the one I've assigned (repeatedly at this point) to be treated as default. I ensured I added custom metadata information to the RPC additional app option, then assigned it as default, which the information is all retained as default but the .exe is not. I've tried unlinking The Sims 2 (Ultimate Collection, specifically) from the metadata database. I even logged out of EA and told my Launchbox to never autoscan for that storefront, to ensure the store scan wasn't what was overwriting the entry. Is there some way to make it stop changing my custom launcher out?
