I have recently installed the game through steam though I have also tried the standalone
and when I hit the play button a screen flashes up before instantly closing.
I am running Windows 7 64bit and I will not upgrade to 8 as I hate it and I downgrades my computer to it.

This is my DxDiag: Here

And this is my MSInfo: Here

Hi,

Make sure you have the latest video driver (NOT windows update driver) download it from the manufacturer website
Make sure you have the latest audio driver (NOT windows update driver) download it from the manufacturer website
Most PC now have 2 video cards make sure you launch Panzar with the strongest video card. Pnzcl.exe is the executable
Make sure start.exe and Pnzcl.exe are added to your firewall exceptions
Make sure that the panzar folder is in you exclusion list of your anti virus C:\Program Files (x86)\Steam\SteamApps\common\Panzar

You are playing using steam.

So open steam
Right click on the game
Choose properties
Go to Tab Local Files
Click on button verify integrity of game cache

Let it finish and try game again.

I have done all you have suggested and no change.
After launching the game I verified the file cache once more and there where 3 files that where invalid this happens
after every time I tried to launch the game.

Is there a way to launch the game in 32 bit mode?

So, your game close after you press the play button.

Right after the closing of the game.

Go on your HD to location C:\Program Files (x86)\Steam\SteamApps\common\Panzar\LogBackups

put all the log files in 1 zip file

send the zip file to community@panzar.com

Hope it will help in fixing the problem
I want to see what this game is like.

So they checked the log files.

There's a string: D3D Error: (Could not find any compatible Direct3D devices.)

That means that the client can't find his video card

Request from the Studio:

Ask him plz to reinstall the drivers on his card

I have reinstalled my driver (did a clean install)
Still closes

I made pnzcl.exe and start.exe use my GPU
and still had the inbound rules in my firewall.

Actually its working now.
Thanks for the help.

Hi,

What changed?

I don't think I properly removed my graphics driver the first time (I think it was the PhysX part of the driver did not remove properly).
So I did it again and it worked this time.
Played it for a bit, been enjoying it.
