Is there anyone who knows how to use this program that can unlock the gmt files for me, I want to convert some cars for personal use but can't get the program to work, maybe because I have VISTA 64 bit. Any help would be great, thanks in advance.

the tool works from command-line.

you can find various other threads where are located discussions about rfactordec:

So VISTA 64 bit would not be the issue, so if I wanted to unlock a gmt file called BMW_a.GMT how exactly would I write the comand when I go to start/run.

while for an entire folder:

Thanks

aluigi, can your tool encrypt gmt file?

rfactordec (and rfactorgmdec too obviously) supports also the encrypting of the file:
rfactordec -e -s 0x2eb8f5cc9b14ea3b input.gmt output.gmt

the number after -s is the signature number of the game for which you want to decrypt the file.
for example the one I used there is that of ARCA Sim Racing, the others are:

Thanks, working well. But is it possible to encrypt a multiple files a time?

just reuse the other bat file you used for the decryption (the method explained in the rfactordec_all.txt text) and modify it adding -e and -s signature after rfactordec.exe.
it's very easy

You right. Thanks you very much for help.

Cheers!
