Can't build any project with UE 5.3 (LNK1181 and other error messages)

Hi,

I can’t build anything with UE 5.3.2 (didn’t have problems in 5.1 and still can build in 4.27 without any problems). I tried to fix the problem, but got multiple different error messages (some related to specific files such as libcurl.lib or delaylimp.lib, others related to some network connection that couldn’t be established and multiple other messages that I could “solve” by disabling basic plugins that are activated by default).

LINK: fatal error LNK1181: cannot open input file “delayimp.lib” < seems to be the most common error…

I tried verifying UE 5.3.2, adding potentially missing addons to Visual Studio and multiple other ideas I found on this and other forums, but I only got other error messages in return…

I can build projects in other versions, just not in UE 5.3 and the error happens even in an empty project.

Any idea what could be wrong or what I could try to fix it? Thanks in advance!

Hey, I was wondering if you had a solution as I am encountering the exact same issue. Cheers

Sorry to say, but no, I didn’t find a solution. Since I’m still mainly working with an old UE 4.27 project atm, I’m just gonna wait with my UE5.3 projects and hope UE 5.4 will work better or someone will post a solution in time…

Thanks for the comment in any case, it’s good to know that I’m not the only one with the problem since this might mean that the issue might be fixed at some point…

There’s many “hacky” workarounds online, but the best solution is to uninstall visual studio completely, restart then reinstall visual studio 2022, check this link out for what optional installs you’ll need also: Setting Up Visual Studio Development Environment for C++ Projects in Unreal Engine | Unreal Engine 5.4 Documentation | Epic Developer Community
