UE 5.3 - C++ Project not compiling

[OAFTLeS]

Hello,

I have been struggling the last few days on some issue after trying to move from 5.0 to 5.3.

1. I have re-downloaded UE 5.3.1

2. I have re-downloaded VS 2022 with the following settings
   

   

3. I am trying to create a new blank C++ project
   This is when I get the first message, could not compile

4. having a look to this “LNK1181” I found that writing in the Library Directories for the project could help but it did not
   

   

5. I tried to compile with VS and got this error:

|Error|MSB3073|The command C:\Program Files\Epic Games\UE_5.3\Engine\Build\BatchFiles\Build.bat WeWorldProjectEditor Win64 Development -Project=D:\01- UnrealProjects\W10-WeWorld\WeWorldProject\WeWorldProject.uproject -WaitMutex -FromMsBuild exited with code 6.|WeWorldProject|C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.MakeFile.Targets|44||

Any Idea of what I could do to solve it ?

Thank you very much.

Did you follow this step-by-step from Epic when setting this up?

Setting Up Visual Studio

If I remember right, I was getting linker issues because I didn’t have the appropriate Windows SDK versions installed that UE requires. I was able to get it to work by following Epic’s instructions.

I also found this older forum post that I believe is the same issue:

Fatal error LNK1181: cannot open input file 'delayimp.lib' in association with attempting to create a new plugin from a UE5 provided template

Im not sure where to debug this, Im guessing that my VS project is trying to build something that doesnt exist, because I highly doubt this “delayimp.lib” cant be found as the unreal project that my plugin is living in was building just fine a few minutes ago with some custom C++ classes I had made in a separate plugin. How would one go about debugging this and digging deeper in the source? Can I configure the build system to provide more detailed data about whats happening behind the scenes he…

Yes, I followed the instructions and I have everything which was listed (and more recent sdk for 2022)

I saw aswell the other subject but did not find “missing” SDK or something.

I found something interesting.

My UE 5.3 did not have the administrator right, same for VS, I had set it and it worked. (at least for this issue)

I’m now back to my first issue: VS not finding my Asset Registry. I will investigate on that one.
