Followed Official Install Instructions / Can't get 5.1.1 to create any C++ project without an error appearing / Blueprint Works / Happening on Friends Machine too

PJGHangouts · May 2, 2023, 1:50am

I’m on a fairly fresh windows 11 install, I tried to install VS2022, and UE5.1.1, I can create Blueprint projects, but any C++ initial project (the right choice, blank and templates) cause an error, and a fail.

I’ve searched various posts, suggesting to make sure SDK is installed (which I did) make sure the .dotnet is in the right location (not x86) make sure the path is set, suggestions like that.

I can install VS2019 and 5.0.3 with no issues, but I’d really like to use 5.1.1.

A friend on Windows 10, tried the exact same install and got the same exact errors, but with me being on the faster internet connection, I’m doing all the TS’ing to see why it’s not working.

It was from a YouTube tutorial that advised using C++ to create, using Blueprints, but having the C++ option.

I tried a blueprint create, and then tried adding a C++ class, but I got a error, telling me it failed, and needed rebuilding, then locks, going back to the launcher and trying to open the project (been calling them TestOne, TestTwo, etc, just for testing) gives me another error, telling me it’s be made in another version, but then fails to load in.

Can anybody help us?

I have access to the log output file on the crash, but the initial black box gives me

An error occurred while trying to generate project files.

Soooooo, turns out.

I was trying to create a project on my D drive.

I created the project in a different folder on my C drive, and it worked.

Go figure!

I also had this happen, and I tried to create the project on my D:/ drive.
After a bit, I figured out the cause was because I had a “!” character in my folder’s name, and it couldn’t find it.

The error that came out was pointing out that the path to “D:/GameDev/GameName” does not contain a .uproject file. But the actual folder name was “D:/!GameDev/GameName”. With the exclamation mark. Renaming the folder solved the issue.
