Hi,
I was trying to learn some basic modding stuff and I followed this tutorial => https://modthesims.info/wiki.php?ti..._Object_Modding

After I did everything according to the tutorial (no errors or warning on Visual Studio) I added my package to the mod folder as usual. When I launch the game, it starts as usual but before even get to maxis logo, it closes itself without any error. I was able to play perfectly before today. I tried to launch it without mods, no difference. In the generated file in the documents, it says:

[Instruction data]
0058d916 => DasmX86Dll.dll not found.

Any idea?

I do not do scripting, but it might help to post in the create/ modding section where various modders might see. Also, I believe, "DasmX86Dll.dll not found" is a generic error. Also, perhaps a pic of your script or object package that someone can look at.
