C++ Access violation writing locaiton

[wolffman122]

Describe what you want to implement and what the issue & the steps to reproduce it are:

auto& factory = Pylon::CTlFactory::GetInstance();
m_Camera = std::make_unique<Pylon::CBaslerUniversalInstantCamera>(factory.CreateFirstDevice());
m_Camera->Open();

When I hit this code on the second line, I am getting numerous Access violation writing locations.

MyApplication.exe has triggered a breakpoint.

If I just choose in the debugger to run, the program will continue and the pylon calls all work. I am able to get images form the Pylon software and while running my own application. Any help would be appreciated.

It seems that you mix 32bit and 64bit code.

Please check your environment that you use to compile.

@thiesmoeller is there a way to set pylon to work with win32 or would i have to go back to a previous version of pylon that supports win32?

[thiesmoeller]

pylon versions are 64bit only for quite some time

If you really are bound to use win32, the
latest version with 32bit support on Windows is 6.1.1
