Creating support for 4 versions of the game, ETS2 62 and 32 bit and ATS 64 bit and unsupported 32 bit would take a lot of time, and ATS only has a supported 64 bit version as they are doing away with 32 bit since they need to take advantage of the extra ram in 63 bit processes. Unfortunately supporting all the versions would just cause for more bugs and issues not to mention, take longer to release. At this time it would be a wise idea to buy a new system or upgrade the current version of your OS, remember, TruckersMP are not paid to make what they are doing so please be patient and remember this is an ALPHA not a beta or official release.
