Downloaded WW2 and Pacific War, both installed without a hitch. Clicked on the Manual, it opened up in a pdf file just fine. Next day, I tried opening the same Manual again, but this time, nothing happened. Tried opening up other pdf files, same thing, nothing would open. Had to reboot the computer in order to open up my other pdf files, but the in-game Manual still doesn't work. Any ideas? Thanks in advance.

Thx for reporting this.

When clicking the "manual" button in the game launcher for the Steam version it comes up fine, and repeatedly so for me.
(I understand this is what does not work for you?)

Are you using the game with Steam, or outside Steam?

This info would help us to hunt down the problem.

The non-Steam version and you're correct, that is what happens.

The new update hasn't fixed the manual problem I noticed.

Open the game installation folder, find a subfolder named "Manual" and open it. Inside you'll find the game's manual in PDF.
