I had the same issue here. Installed the new beta today and after installing, nothing. The game rufused to start no matter what I did. And yes it did work fine before the update.

What I did to fix it?

1) Click the Stardock logo icon in the upper left.

2) Click on Preferences.

3) Click on 'Reset Data'

4) Impulse will reset it's config data and force an update.

5) Allow the update to finish and restart Impulse and your done.

6) It *Should* work fine after that.

I have no idea other than what I tried myself with the reset data option. The reset data option usually fixes 75-80% of the problems when games that use Impulse won't work.

You could try relogging and see if that works.

If you're running Vista run demigod in administrator mode (I.E. right-click on demigod.exe and run as administrator.)

Instead of running the game through Impulse find the menu shortcut and run Demigod from there, or just run it from where the game was installed too. (C:\Program Files\Stardock Games\Demigod)

My main question would be, did you install anything in the meantime between the 2 betas, like some other program that may be affecting Demigod from executing.

Hmm I don't know if you did this but depending on what OS you have try updating the system video, audio, and directX drivers. That would be my next idea anyway.

Unless I knew specifically what you had running for services and applications it would be hard to diagnose what's really going on.

Well, I give up... Here is my DxDiag. I don't know what made Demigod impossible to launch.

Hi ,

I appear to be having the exact same problem. The 2x betas were running fine but 3 won't start at all.

My system spec is:

Vista home premium

AMD phenom 9600 

2GB ram

Nvidia 8800gt latest driver

One thing I have in common with the above poster is that I'm also running Comdo Firewall. Could this be a potential issue?

I'm not seeing any log files produced in the Demigod folder.

I uninstalled and reinstalled the game without success. Ran the game as adminstrator from its bin folder.

I will try resetting Impulse but I doubt that will help.

Well I just verified it. It seems to be Comodo that is the problem. Simply shutting it down doesn't solve the problem. I completely uninstalled Comodo and now the game works fine. Try it and see.

I may download the latest comodo installer and try again as I know it did a few auto updates this week which may have screwed things up. 

If it still doesn't allow the game to run then I'm not sure what the problem is. I already ditched Zone alarm because it conflicted with other software. 

Update: Ok so I downloaded Comodo's latest 'internet securilty' app and installed the Firewall component and now demigod fails to run again. So at least on my end I seem to have found the issue. Although I'm not sure why only demigod is having trouble with comodo. Everything I've tried seems to be ok.

Interesting indeed. I am running the latest version of Comodo Firewall and have had no problems with it. I wonder if just adding the Demigod.exe to your 'Define a New Trusted Application' list that would have solved your problem. It's a shame you had to actually uninstall CF to get the game to work properly. Actually the Defense + function is quite useful....sort of a failsafe for application execution and to protect the user from unauthorized programs from infecting your computer. Alot of new anti-spyware and anti-virus programs use the same technology called HIPS (Host Intrusion Prevention System). Any time an unknown program is executed you are prompted to either allow (if you know it to be safe) or disallow it. ZoneAlarm,Comodo Firewall,Comodo Antivirus,Spyware Terminator, etc all use HIPS.

Well anyway, I'm glad you solved your problem.

Well Demigod was in the Trusted Application list of the Firewall and the Defense+. I really don't know what caused this...

Yep that's the version I got. And Windows Firewall is disabled don't worry. I may try to reinstall Comodo with Defense+ when Demigod will be released but for now, I'll leave it as it is now (well Demigod still doesn't work for some obscure memory reasons but I can launch it... ).

I tried all of the above steps, reinstalled to the latest version of CF. Added demigod to the trusted list on both firewall and defense+ and then disabled both and exited the app. Demigod still won't work once CF is installed with Defense+.

It may be useful for the devs to try out CF with the game to see why it falls over and if it's preventable. While it could be an issue with CF, there may be a crashing bug in the game that can be knocked on the head.
