I have a 64bit laptop and as far as I know I installed 64bit TS2020
But this morning, when starting up TS2020, there was an image of a train popping up (very briefly) with the text "32bit"
How do I double check I indeed have the 64bit version of TS2020 installed and not the 32bit ?

Above image pops up every now abd then after clicking the Tran Simulator short cut (also visible)
