Hitman 1 progression not syncing with Hitman 3


I have HM1 and recently purchased HM3 with the add on of buying HM2 to carry all the progression of past games. I started HM3 to continue playing my HM1 from there but it shows that I need to purchase HM1, even that I have it. How I can fix that?


Platform? Is the HITMAN 1 DLC installed?

PC. I only have standard game.
