2015 OpenGL

EMCat

Hi everyone, I have been searching for a lead but to no avail so I think I'm asking this one. I'm quite bothered why my sketchup 2015 won't run OpenGL mode with my Nvidia GTX660m on my laptop. It only runs on my integrated card (Intel HD4000) I have had no problems running it with the previous versions and I can even run it simultaneously with an older version and still have the older one running the high performance card.

Things I've tried:

Right click>Run with (High performance Card)
Set Nvidia as default for sketchup in nvidia control panel
Set Nvidia as default for all
Disabling the intel hd4000 in device manager (crashed my display)
Used Nvidia Optimus test to check the state of GPU (still OFF)

I can't "visually" test the cards by enabling and disabling the openGL since disabling the OpenGL will run sketchup in the onboard graphics card (Microsoft GDI Generic 1.1)
Is this a bug? Because I could use the additional rendering power aside from the ram advantage from it

Laptop: msi ge60
i7 3630qm win 7 x64
16gb ram

2015

Additional:

I "tested" if it was using the Nvdia through the Optimus tools to detect the GPU's state.
Ran 2014 and the state went "ON" from off
Ran 2015 and it remained "OFF"

SOLVED

Just in case anyone is having the same problem is mine. Apparently the problem was that Nvidia (some gpus) forgot to sign a dll pertaining to x64 programs and will not run any x64 using nvidia gpu. the fix is found within the registry (Might not be applicable to all)

I found this on nvidia forums

"set the following keys to 0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\RequireSignedAppInit
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows\RequireSignedAppInit"

works directly without reboot.

Thanks for sharing your solution.

I'm running a 7 series and a 5 series and I don't see either of those reg files in my system on Win 7 64bit.

I'm sorry to hear that Krisidious, guy who shared this had Msi laptop too, so I guess that's one case.

Could be a laptop thing. I don't think that I'm having any issue though. Just wanted to make sure.
