Hello there guys, well I have the same error , and it started after I updated the Nvidia GeForce driver version from 320.19 to 320.49 . This error comes out when I try to run a game mostly and gives me option to press button "OK" after I press the button nothing happens , it let me play normally , but this damn error is borring and I would like to fix it. I noticed too the error comes out when I try to run software " GeForce Experience " . And LookinAround , I gave a try with dxdiag and when I wanna run it the same error comes again out but from other directory , its not system32 , its SysWOW64. Look at this image :
btw I Uploaded the dxdiag file , so you can read inside. I installed Process Explorer and searched for nvspcap.dll and it didnt found the file. Like this file is not exist , I dont know anymore what could be the problem.
I gave a try with right click on system32 but there are no nvspcap.dll files on the list , only system32 folders with different dates.
Do you have any idea ?
