I am getting this when trying to run a stand alone install. My system is as follows:

Acer Aspire 7540

4 GB RAM
Win 7 64 bit Home Premium Service Pack 1
DirectX 11
ATI Mobility Radeon HD 4200 Graphics Adapter

Also getting this error...

Windows 7 Pro SP1
DirectX 11
Athlon II X3 450 processor
4GB RAM
Nvidia Geforce GTX 550 Ti

Nice quick downloand from Steam, unable to run the game though...

Guys above: try setting DPI scaling to default 100%. I was using custom 149% (since starcraft 2 has a non-working mouse at 150%). Changing back to 100% solved the problem above

Devs: is there a way to fix that in a patch? setting dpi back and forth requires 2 log-off log-on actions in windows and is not very convinient.

Windows 7 64-bit version here and it works, so I guess that your problem is either video drivers or directx.

Try to install latest drivers for your graphics card and install latest version of DirectX 9:

That sounds strange. We'll look into it... Thanks for letting us know!

Update:
It is indeed strange, as I reverted back to 149% DPI and the game is launching normally. Maybe it must be done only one time, or it is completely unrelated and something else fixed my problem. I cannot guess what, as I didn't make any other changes to the computer.

Running custom resolution of 1360x768 via HDMI, the actual native resolution of my LCD tv which Windows 7 doesn't seem to recognise properly. Played many games from Mass Effect to Avadon, via Dragon Age etc. and never had this issue.

Could you try running the game in windowed or borderless mode (in game options)?

I was already at 100% DPI, so I set it to 125% and logged off/back on. No good.

Set it back to 100% and logged off and on. Still no joy.
