Now look, you're not giving any proper information at all. You just say you got a 2017 mod, which I assume isn't CSM, that you want to update to 2018.
Rather than having a look at the FAQ (which seemingly absolutely noone does), you just hijack a mod thread to ask a question that (seemingly) isn't related to the mod at all.
So, here's a guide for how to install GP4, official patch, no CD.exe and gpxpatch [
www.grandprixgames.org]
(Important note: don't install it to the default Program/Program Files folder, create a new directory e.g. C:\Games\GP4)
(Additional note: the pre-patched version from GP4Central is no longer available)
Here one for ZaZTools (essential for mods): [
