    Laptop problem with NVCPL.DLL

    got some problem with my laptop for a good 1-2 month.

    Each time there is a new driver, I uninstall it with DDU and reinstall the new one

    But since a while, I get an error for NVCPL.DLL

    I install the driver, like 368.69, and everything is fine if I dont reboot. Nvidia control panel is there, I can assign my GTX770m to a game, etc

    As soon as I reboot, I get the error, can't acces NCP and games runs only on my integreded GPU instead of the dedicated.

    Help would be appreciated thx

    * I can't install neither Geforce Experience because I get an other error at startup
    ** ran CCleaner to get rid of bad things... without succes
    *** win10 64bit

    Remove the onboard gpu drivers and see if that helps. I would also go back to
    your laptop website and use their NVidia driver listed that may help also. You don't always need the newest NVidia driver out especially for the 700m series.

    no I meant remove any drivers not used by the NVidia card. Like my laptop had intel hd 25xx etc. I meant remove those drivers so the NVidia card is only gpu with drivers on the laptop. IF MSI has not updated their site then I suggest going back to the drivers your laptop was most stable and keep those. Driver update are for the newer cards and all their bells and whistles. The 700m series has been stable for very long time. Try to go back to most stable drivers you used. SEE BELOW FIRST I THINK I FOUND YOUR PROBLEM.

    When notebook has two videocards - one integrated and one dedicated - integrated one is always in use because it interoperates with display, and dedicated one interoperates with integrated. They can be called as primary (integrated) and secondary (dedicated) videocards. Windows will fail to display any info without primary videocard. So I understand it.

    You provided a link to Visual Basic redistributable files which are of no use to software which was not developed in that language.
    I have checked "nvcpl.dll" for a dependencies and it doesn`t depend on any of C, C++, VB libraries.

    I realised I didnt mentionned the exact error I have....

    It's in French, but basically it's:

    Problem at startup of NVCPL.DLL
    Acces Denied

    Dont know if it would help...

    Thx for trying anyway :)

    i'm not giving up on you....try using a registry CLEANER AND REPAIR see if that helps. Have you tried using system restore back to a point where everything worked fine? That would repair files that may have been corrupted or erased.
    Did you try the download it said that you may be missing a file that you need to make NVidia work but it's up to you. Also I found this site...http://fix4dll.com/nvcpl_dll it has a download for dll directly.
    And when you go to download the Nvidia drivers click on box that says to do a clean install. It then erases ALL it's old Nvidia files and then puts down fresh ones. And last but not least try using Microsoft itself to help you, in command prompt use scanreg/fix .

    I already tried everything you said except system restore because I dont remember when it started...

    Anyway, kinda fedup with that **** with half the thing working on win10

    Do we have an estimate/rumors when should the 10**M GPUs be availalble?

    I would go to device manager and click on each device and check for driver updates. It is tedious work I know but it may help.:bang:
    Also, go to windows-program files-(not 86)-nvdia file- control panel-check to see if these three files are inside the folder: nvcplui-nvcpluir.dll-nvgpuUtilization

    And also I found a file folder inside Nvidia program that uses runtime, the folder is MSVCRuntime, did you ever try to download the runtime files?

    yep, waiting to see how those new MGPUs are going to perform

    but what is frusttrating is that everything works until I reboot :bang:
    I install the driver, NCP is there, I can open it, change settings, etc
    Like it should
    As soon as I reboot; BANG acces denied........ :finger::bang:

    Looks like a permission problem, are you logging into a TEMP profile by any chance?

    wow! OK, so .dll=dynamic library link. When files are downloaded fresh they work until you restart your windows your access is denied....So go back to Nvidia control panel folder, right click on nvcpuli and click on run as administrator. See if this fixes the problem. :3eyes:
