[SOLVED] 2.18 to 2.19.1 migrating engine init error.

[bboguni]

I'm migrating the engine version from 2.18 to 2.19.1.
However, I've encountered a problem.

I'm trying to use the engine using InitParameters in version 2.19.1.
The engine initialization logic below is loaded normally in 2.18.
However, an error occurs in 2.19.

================================================================

std::vector<std::string> args = {
"temporary.exe",
"-data_path", ".\\data",
"-video_app", "dx",
"-engine_config", ".\\data\\unigine.cfg",
"-extern_define", "MENU_USER,MOUSE_USER",
"-console_command", "world_load \"basic_world_0.world\""
};

std::vector<char*> argv; 
for (auto& arg : args) 
argv.push_back(const_cast<char*>(arg.c_str())); 

int argc = static_cast<int>(argv.size()); 

Unigine::Engine::InitParameters init_params; 
init_params.system_proxy = &systemProxyKovi; 
init_params.window_title = "temporary"; 

this->m_KOVIEngine = Unigine::Engine::init(init_params, argc, argv.data());

================================================================

The following is the call stack information where the error occurs.

Hello!

Try to update Microsoft Visual C++ redistributable package to the latest version: https://aka.ms/vs/17/release/vc_redist.x64.exe (14.40+ is required).

Also, please make sure that engine is loading new version of visual studio runtime dlls from the C:\Windows\System32. Sometimes it can load old version (like 14.29) from different location and crash.

Thanks!

It works perfectly. Thank you very much!!
