I started to get an error when trying to open c++ projects after instaling unreal engine 5.5 and MSVC (The log said the previous version I was using got banned), I’m not sure if it is related to the update but i’m sure it was not happening before (It’s happening in all unreal engine versions). if you know the solution, please help me
Hi @Vinipiterson,
That sounds like you need to upgrade your Toolchain. I had a similar error popup. I upgraded my Visual Studio to the latest version and it worked fine after that. I think MSVC 14.40 and a few below are banned.
Some compiler notes that may indicate the cause
Note that __has_feature and __has_extension are not recommended for use in new code, and are only provided for compatibility with Clang. For details of which identifiers are accepted by these function-like macros, see the Clang documentation.
So maybe with 5.5 there have been some updates that depreciate the use of __has_feature
Try updating your msvc to a newer version if yours is no longer seen as ok.
Also take note of the warning in your solution
Usually installing components fixes sudden weird errors like this.
It should update / install missing dependencies.
Thank you so much! I completely reinstalled visual studio following Setting Up Visual Studio Development Environment for C++ Projects in Unreal Engine | Unreal Engine 5.0 Documentation | Epic Developer Community and downloaded the components visual studio asked about and it worked.
