How to make a copy of MB Truckracing

[maxi]

Please help me!

I tried to make a backup copy of my Mercedes Benz Truck Racing.

I found out so far, that there are 4 dummy-files, each about 600 MB.
I replaced them by zero-byte-files and burned the CD.

But by trying to start the setup-program, I get the message: "This is not a valid 32bit program" (or something of that kind).

What can I do?

Also having trouble copying this.have found the dummy files but still cant burn working copy!
willkeepyou updated if I find anything>
