4- Downloaded JSGME and made it point tom y Il-2 1946 folder

9- Put HSFX History Mod in JSGME. Tried to launch HSFX 4.1. Nothing happens

Question: should I install the fix from here? (The link is inoperative)

Step 4 was not necessary, since HSFX included the JSGME.
Yes, install the D2D patch. It should fix things. Ideally, it should be installed before installing HSFX, but doing it now may work.
