I just installed it and I have no luck starting the game. Launching either the "Launch Pax Imperia" link or the actual executable file does absolutely nothing, although the game appears in the processes tab of Task Manager.

Is it happening for you guys as well?

I wrote to the Support team, hopefully they will be able to help me!

Some questions:

Did you install dirext 9.0c?

Which OS do you use?

Do you have any error-message?

Do you have admin-rights?

I am the same it just starts up, nothing is shown but it is in the task list.
I have a CD of the original game which works if I use DxWnd but the GoG version doesn't work with DxWnd at all.

My problem I feel is I'm running windows10 (My assumption is win 10 wont be supported for quite some time) :/
Oh well I'll just stick to the CD version.

Unfortunately this seems to be the only solution for Windows 10 users at the moment. Hopefully you guys will be able to provide a fix of some sort. Fortunately, I also have a Windows 8.1 machine :)

I tried all the compatibility settings down to Windows 95, but nothing works. It seems like removing that .dll is the only fix for now. It's a shame though because the music of the game is awesome :(

Cheers for that now I can play :D
I can go put the music on in the background small price to pay to play the game without external programs

i am glad to read you can play it, but i assume the (intro) videos wont work on win10 like on 8.1?
if so then you wont have music and no videos, thats kinda sad to read.
anyways i stick with 7 till it its gone (2020)

Spot on. I'm sticking with Win 7 64 bit. :)

thanks for the reply.

i've been using windows since the first win95 , also played a few months with win3.11 , but then again i also followed a class for lotus 123 (old spreadsheet) even got my certificate, i got an 8 so that was a pretty nice score (max is 10)
of course it is ancient and redundant now but it was fun to to learn it in the 90s.
So i have been around awhile regarding windows.
I have to admit that basically windows is going 'down the drain', its logical that old win has to move along with nowadays designs and flat design (mobile/touchpads and the likes) so its new look, looks like crap.

icons that look like smileys and simple 1 color logos that were used on soapbrands.
But we have to move on and we will have to use this modern stuff sooner or later, whether we like it or not, so it will be later (much later) then sooner for me.

Its also clear that MickeySoft has made win10 to support lots of Xbox stuff and other console supporting and streaming stuff, and mobile devices, so i fear that windows looks more like console stuff then a decent OS.

Just a heads up: if you have Win 10 you can also copy the winmm.dll file from your Windows\System32 folder and replace the one contained in the game directory.

However you will still be unable to play the game's music or the FMVs.

It would be interesting for someone to actually compare the two files and see the differences. Maybe they can find a solution this way!
