More than welcome guys.
Just a quick heads up to both of you:
I don't use CSM (other than when I'm installing a brand new mod for the first time), because I'm primarily Linux user and CSM doesn't work well under WINE.
Point is though, once I have the mod up and running how I like it I save the entire game folder as a zip file and I renew the zip each time I play a season, to update car setups or maintain improvements I've made etc.
So what?
Well I haven't re-installed GP4 since about 2007. I just unzip the mod folder I want to use and get racing.
Plus, if you use the same game folder name for all your mods, you'll never get those annoying registry errors either.
(Keep a default GP4 installation zipped up too, for CSM to work with when you install a new mod - the
patched one on GP4Central is a good choice).
I'm not necessarily saying it's the best or most efficient way of doing things (I actually de-CSM all the mods I play to save space eventually), but it works well for me and it might be worth considering if you have the storage space. These days I have over 40 'installations' zipped up and ready to play in a few seconds and I never get any problems at all. That said however, even if you only have space to keep one working installation zipped up, it'll help you with your fault finding next time you do get an error.
