Confusion about builds regarding v4.5 HF1

Postby upnaway » Thu May 16, 2019 12:14 pm

Hi there,
I've noticed that HF1 for v4.5 has been released.
The post confuses me, however.
The hotfix update to Prepar3D v4.5 ( is now available
The newly posted Prepar3D v4.5 ( Full Download on the Purchased Downloads page includes the Hotfix.
1) Is the old or the new release?
2) Does only the Full Download contain the HF? What about the Individual Component Downloads?

Sorry for the dumb questions but I am still a rookie concerning P3D and its software structure.

Hello Michael,

v4.5.12 is the new hotfix version. There is no longer a download for the original 4.5 client. Only the hotfix version is in both the full and the individual component downloads.
