Ok, for what it's worth, here's me again.
I restored my pc from an image I had, I reinstalled the Autoupdater (Python, etc...) from scratch, restored the 20Gb of ABB content from a backup, formatted my "games" hard-disk, recreated a
new "GTLABB" folder, and I
still have more than 7Gb of local files to reinstall.
Not 20, not 15, not 2, always 7, so there must a problem with some specific cars, and not with all of them.
As an example, here's two shots of the zip with the first car that Autoupdater wants to reinstall, the "Fiat_Abarth_Pizza_V1_1".
In the screenshot at the top you see the content of the downloaded zip, at the bottom you see the content of the actual car, as it is in GTL.
The only difference is in the selected file: 1,67 Kb VS 1,65 Kb.
I manually unzipped this car into GTLABB, thinking that this little Kb difference was the problem, but, guess what...nothing changed.
I could maybe try to delete this Fiat from my general archive and see if it works after being redownloaded.
If it is a folder access problem, how can i "Run as administrator" the Autoupdater, which is not an exe? Right click doesn't show the option.
I'm the only user on my XP machine.
Apart from wether I have problems online or not, isn't that strange?
