ENV PATH Variable Issues

[quazi]

So I have maxed out my env var path length in windows and have not hacked it in registry to accept more environment variables in the path.
My question is how do i re-run the env variable insert stuff that automatically happens? Or better yet.

What are those variables?  .. Because builds don't work for me due to the engines path vars missing i think.

See the section called "Environment Variable" on this page:

This has all the information about it.

Getting a strange new problem when trying to compile on Visual Studio Enterprise 2022 with the proper VS Installer options selected. When i go to run the SLN and compile the binary I get the following error:

```Error Code E1696`cannot open source file "atlbase.h"```
```Error Code C1083`cannot open include file: 'altbase.h': No such file or directory````

And i can confirm that the env is set. However it did set it with the slashes the wrong way / so i fixed it to \ but same issue.  Tried a new project from scratch.. same problem. Do i need to use 2017?

No, you should be using Visual Studio 2022.

It's important to have "Desktop Development with C++" installed:

I have that installed from pointing me to the right doc earlier.

It seems Unreal engine 5 and some of the plugins were not playing nice with the Ultra Engine. So i had to uninstall everything in 2022 and reinstall just the c++ desktop development. The build is compiling now thanks!

As of version 5.0.1 we no longer use an environment variable for C++ compilation.
