Hi, There does not appear to be a 2021 User Guide in the "Manuals" section of TS2021 all the previous years are there. Is there one due out soon? I am using the 64 bit version. MTIA Geoff.
You may be using the 64 but version but there is no different to the 32 bit version. DTG produced a guide and you can download it on the Steam page https://store.steampowered.com/manual/24010 I don't there is much new in it.
