So i have a little cloudbook made by acer and I needed to put window's 10 back on it so I installed the 32 version of it.... and just for s and g's of it i stuck a downloaded copy of tis2000 that i had on a flash drive in it.. and I do know that it is suppose to work only with win xp and 7... well the program downloaded flawlessly the dongle crack downloaded as well.. when i down loaded it to my win 7 laptop i kept gettin window's kill program,,, and i was having a hard time opening the sps,,,, i never got a kill program when i put it on the windw's 10 and i didn't have no trouble with it working and it opens every time with no issues.. so i am kinda confussed I thought it wasn't suppose to work on window's 19
