Qt5WebEngineCored.dll crash

[Good Guy]

I try to use Qt 5.7 (and 5.6) on Windows 7 with Visual Studio 2015. I receive following error when I try to open any web page:

Exception thrown at 0x0000000000000000 in MyProgram.exe: 0xC0000005: Access violation executing location 0x0000000000000000.

Call stack doesn't contain any custom code:
