Thanks a lot for posting this. I have both VS2017 and 2019 installed (w/ all the settings specified in the official VS setup instructions).
Recently merged 4.25.4 release into a custom fork that has new shader models.
Using ryanjon’s UE4 binary builder to build, I got that **PDBCOPY.EXE **error.
I have 3 different Windows SDKs installed.
10.1.17134.12
10.1.17763.132
10.1.18362.1
I modified (added Debugging Tools for Windows) only on 10.1.18362.1, and it went through.
Note: In the UE4 Bindary Builder app, I enabled Use 2019 compiler, because ever since 4.25.3 I haven’t been able to build the engine with VS2017.
