I write a sample program, custom a subclass of AIS_InteractiveObject, and display. when i run this code in a pc with GPU Intel770, it is ok, but when i run in a pc with GPU intel 770 and nvidiat1000, it collapse, and i get info : "An exception occurred at 0x00007FFD09C711B2 (TKV3d.dll) in ...exe: 0xC0000005: Access violation occurred when reading location 0xFFFFFFFFFFFFFFFF. how to resolve it?

If you think crash happens due to using of another graphic driver (nvidiat1000) - check driver updates, report bugs to the vendor.
If crash happens somewhere in OCCT - prepare OCCT build with debug symbols and analyze stack trace carefully. Most likely you will easily find the root of the problem in your code (like some uninitialized properties, NULL pointers, etc.).
Without code sample to look at there's nothing to suggest more.
