I installed 15 files at one time.. 3 showed up the first time of them... then 2 (Picture) yes they say I installed again cause I did it twice to make a picture... when I click on one of the not shown files single it says its installed though... but why isnt the window showing all at the same time if it did install it too? It is confusing...

That is one reason I don't use the launcher for anything but worlds. I turn all my cc into packages with the Multi-extractor https://modthesims.info/d/364038/de...-sept-2009.html

With 158 new files that would take years cause the installer is pretty slow... Oh you can turn them in to packages? Thanks for telling

I can open just 15 files at once cause after that I dont have the "open" option anymore for all selected files... I never had issues with that befor and for sure more then 3 files got installed... weird...

Since The Sims 3 allows you to install Sims3Packs while the game is open, you could load the game and then the launcher to install things. Since the longest part of the installation is waiting for TS3/TS3W.exe to load, having the game open already should make it faster. Then you can click Install on one item or select several items, then immediately check whether they show up in the game.

Wait thats a thing? Need to try that out next time! Thanks!
