For all you blaming drivers, microsoft, etc (and not the real culprits FIRAXIS WHO SHOULD HAVE HAD THE FINAL VERSION QUALITY CHECKED) want to hear a kicker?
My main desktop computer is similar to Liquidsword's--ATI motherboard and exact same vid card--X700 Pro 256 meg card. I had the older (I believe 5.8 drivers--they were only one version back) installed on this computer and my wife's laptop (the OMEGA driver version on BOTH computers). I installed CIV IV excitedly, screen starts to load, BAM! back to desktop (no error message or anything). Ok, try to go to Firaxis support for this game,wow, no support forums even up...so I came here, read all the posts about latest drivers and I tried the 5.10 drivers. Still no joy, but now I get the failed to initialize renderer message just like everyone else. Come back to this forum, read about the "possible fix from Firaxis (LOL yea, riiiiiiight)" and I use both ATI's driver cleaners and another 3rd party driver cleaner program (as well as checking add/del programs just to be sure). I reboot, reinstall 5.10 drivers (both Omega and ATI's base 5.10 version off their website) and still no joy. Ok, I figure maybe a problem with DX9c (even though 2-3 other brand-new games don't have any problems whatsover) I go to Microsoft's website and download the latest version of DX9c--still no joy. Wow, built many computers from scratch and been gaming for 28 years and never had any problems this major just getting a "main stream" title to just START...hmm...frustrated, I figure I'll try it on the wifey's laptop, which ALSO HAS AN ATI VID CARD.
Keep in mind, her laptop was in the same "state" driver-wise as my desktop was before I first even tried to install CIV IV on my computer (same vid card driver version/type as mentioned above, same version of direct x). For S & G's I go ahead and install it on her ATI-video laptop--THE GAME WORKS FINE--SHE GOT TO PLAY IT FOR 3 HOURS WITH NO PROBLEMS WHATSOEVER! Karma? Perhaps... Silly and not ATI, microsoft, or anyone else's fault but Firaxis and Take Two (last time I checked, publishers don't do programming--but possibly an error in manufactoring (not likely...but hey ;-)
Anyway, so for ME (and everyone's computer is going to be slightly different with different components) It made no difference what drivers (ATI, OMEGA, completing driving cleaning, old/new driver versions, or re-downloading direct x) on my desktop with ATI X700 256 meg pro...
HOWEVER, on wifey's ATI 9700 mob 128 meg laptop, game worked fine IN THE SAME STATE MY DESKTOP WAS (same drivers, direct x, etc) WHEN I FIRST TRIED TO INSTALL CIV IV (before trying all the suggestions on this board). Very, very, weird... ;-)
Thanks to all for the great suggestions and possible fixes though, very friendly board and I do appreciate the help from the CIV IV player base (even though Firaxis/Take Two don't even have a support forum up yet for a released game!)
I'll try to do what LiquidSword did (uninstall CIV IV, do complete driver clean again, re-install 5.10 drivers and see if this fixes it on my main computer...) Not likely as it may have been just coincidence with something else he did, but worth a shot
Thanks again for the friendly tips, I'll keep plugging away while I watch the wifey play my birthday present (yes, the game I choose to buy on my b-day didn't work ;-) and I'll fix Firaxis' boo-boo ;-)
Regards,
Hoya
