Several users notified us that the Medusa demo was not running for them and we discovered the problem. Under Windows Vista 64-bit our installer package just not including the C++ 2005 SP1 runtime needed to run the demo.
Simply download it, install it, and then install Medusa. Please let us know your results!

mine is windows 7 (32-bit) and i have nvidia g-force 7300 it shows that displayArgs.txt file not supported and so on. plz help

The demo workls fine on Win 7 64 bit with a GTX 275. I had to install ...

and

Why can't we download the dll and set our environment variable to path to it?

Test System:
i7 920
Asus Rampage 2 GENE
Corsair TR3X3G-1600C8D (8-8-8-20)
[ SLI ] 2 cards MSI Nvidia GTX260 T2D896 oc
Corsair CMPSU-850HX
WesternDigital 500Gb SATA2 32bit
Pioneer DVR-S18
Thor's Hammer S126384
from my point of view, I was surprise this was better compared when i run on ATI Radeon. To be honest ASUS need to improve NB heatsink. The graphic shows in this cinematic demo is crisp enough to shows us what SLI can do cause i run AntiAliasing 16xQ and still no flicker. I test Farcry2, NFS undercover, and Granado Espada online, all with maximum setting also experienced free flicker gaming.

I have just installed the runtime and the dx9 update both after installing the medusa demo on my win 7 x64 machine with no issues. I must say the demo runs pretty flawlessly on my system, i7 920 on ga-x58-extreme, 2 x gtx280 in sli & 6gb ram ... pretty impressed nVidia pplz ... xD

Windows 7 RC (x86) users.
If you recieve errors starting Medusa, (missing dll's, bad or missing displayArgs.txt file, & side-by-side configuration error).
Install both: the "C++ 2005 SP1 runtime" from link above (Adams's post), http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647&DisplayLang=en ,
And MS's "DirectX March 2009 Update", http://www.microsoft.com/downloads/details.aspx?FamilyID=2da43d38-db71-4c1b-bc6a-9b6652cd92a3&DisplayLang=en
These will install missing d3dx files, & also the missing SxS entries for vc80,mfc,ver, that Medusa is looking for

Same problem here Vista 64-bit, GTX 285. I wanted it to show me what it could do, an error box was not what I had in mind.

Using the link supplied by aarondr fixed the issue on Windows 7 RC 32 bit.
I'm sure there's a lesson to be learnt here...never trust a woman ? ;-)

You shouldn't name this Medusa thing as "technology demo", because if this is the technology of future nvidia cards, we have serious problem :(
I couldn't run it on four different machines. 2 Vista and 2 XP. Please publish a service pack or something that contains everything necessary. I ve setup almost all the versions of service packs and redistributables, net frameworks etc. on all my systems. My systems have turned into trash. Still either d3d10.dll or some d3d10core dll is missing. I copied everything everywhere and finally achieved a "nothing to do" kind of message: Some point cannot be found in some dynamic library ... This Medusa sucks!!
May be all this is about the myth on medusa turning people to stone:
By the time you get it right, all the curious downloaders of the demo will be patient like stone...

Download the DirectX SDK, after update or install, it works fine!
Posted by: James | January 31, 2009 at 04:18 AM
Please try use Windows XP to see if can running Medussa Demo on it! I heard somewhere tweaks & trick for XP can upgrade to Directx 10 and running without problems! I can't believe demo will work on XP. Microsoft need release Directx 10 for Windows XP soon.
I heard someone said that Microsoft try fool you to upgrade Vista. MS force you to change Vista from XP. Sound stupid things from MS. Private company will try fix problems with Directx 10 for XP when will be release out soon. Not so long to go. I wait for XP to update. I hate Vista because eat whole memory ram and hard drive space. Vista is full of junk and waste money.

The Update For The DLL Error does not correct the issue in Windows 7 64-Bit
Posted by: Paolo | January 16, 2009 at 08:05 AM
Well, on 2-2-2009, the latest Win Vista updates, and the latest Medusa demo still produces the error that d3dx10_37.dll cannot be found. This is with the runtime C++ installed. There are sites on the net that will help you with this if you do a search, but the originators of the programs should also solve the problem>
Posted by: FALCON | January 02, 2009 at 07:30 AM
Dx3dX10_37.dll is from the March Distribution of DirectX10, however all previous redist packages have all of the old ones so June should work.
Try searching for dx3dx10_37.dll on your computer or opening
C:\Program Files (x86)\Microsoft DirectX SDK (June 2008)\Redist\Mar2008_d3dx10_37_x86.cab - if you have the SDK
Then copy it into the directory the Medusa executable is installed to.

Doesn't work after installing that runtime. Error: "This application has failed to start because d3dx10_37.dll [...]"

Installing the June 2008 updated runtime fixes the issue:

The problem is still there -- even with the redistributable. Result is "d3dx10_37.dll was not found".
