You're running Optimus on your machine which is causing the issue. We've experienced the same type of issues with over 40 Dell Precision 6600 laptops and to resolve them we disabled optimus.
NVIDIA Optimus needs to be disabled from the bios. While in the bios, navigate to Video > and uncheck Use Optimus...
Once you reboot the machine, you'll need to adjust your screen resolution. Every application you run will now use your NVIDIA card without any problems.
I also have a problem with starting Inventor 2014. I finished instalation, everything works except for Inventor. I mean, DWG TrueView works, ReCap works, Vault works, but the main software doesn't. When I try to start inventor all I get is this windows opened. I downloaded it like 10 times, tried to instal it directly at first, then I tried downloading it first. I allways get the same result.
I've seen this behavior with AntiVirus applications--more specifically "Trend Micro". Disable the antivirus application and run Inventor again.
Are you using a Dell laptop? Right click the Inventor shortcut from the desktop and see if you have "Run with Graphics Processor" in the menu. When you hover over it, you'll see two graphics cards (Intel and NVIDIA), choose Intel.
If you have this option in the right click menu, it means you have Optimus enabled. You'll need to disable optimus from the bios during the boot up of your machine.
Let me know...
