Hi, I keep getting this error when I try to create a c++ project, does anyone know the answer:

An error occurred while trying to generate project files.

Greetings @jaberhammoudeh1

Welcome to the Unreal Engine Community Forums! I’d be happy to take a look at finding the issue with this. I’d like to start with seeing what system specs you’re currently running on the machine that is receiving this error. Another thread I pulled that has a similar error I also found that you might be interested in here. I hope this is helpful! If it’s not resolved from the link, respond back with the specs and we can go from there. Thanks!

Thank you for reaching out, I had put the dotnet file to programs x86 and got this massage after trying to create a c++ project:

Have you tried downloading the newest versions and reinstalling Dotnet itself yet, by chance? The errors listed seem to be revolving around loading files from your dotnet folder.
(I’d also try running UE as administrator prior to downloading/installing the latest Dotnet)
