Concerning messages during UE5.1 source build

I’m in the process of building ue5.1 from source and during compilation I get these two messages.
Unable to read D:\Unreal\UnrealEngine\Engine\Intermediate\Build\SourceFileCache.bin. See log for additional information.
I get that before it actually starts compiling and then about 70 actions in I got
Touch msado15.tlh: Exited with error code 1
1> Touch msado15.tlh: WorkingDirectory D:\Unreal\UnrealEngine\Engine\Source
1> Touch msado15.tlh: C:\WINDOWS\system32\cmd.exe /C “copy /b “D:\Unreal\UnrealEngine\Engine\Plugins\Runtime\Database\ADOSupport\Intermediate\Build\Win64\UnrealEditor\Development\ADOSupport\msado15.tlh”+, “D:\Unreal\UnrealEngine\Engine\Plugins\Runtime\Database\ADOSupport\Intermediate\Build\Win64\UnrealEditor\Development\ADOSupport\msado15.tlh” 1>nul:”
If either of these are problems it’s not enough to stop compilation but I’m just wondering if it will cause problems down the road.

Hey there @fgvand944! So I was unfamiliar with this specific DLL so I did a bit of background research on it. Seems like a library for referencing data, it might be relevant to the packaging process, so if at all possible attempt package a simple project to see if there’s any major issues.

Can’t find any similar results to this online, it would be a needle in a haystack if it packages well and you assume it works. Does the file exists? Do you have read access rights? couldit be locked by the antivirus?

Thanks for the info. I’ll package a project and see if I have any issues.

It does exist and I appear to have read access to it. I did download a Directx12 sample project from microsoft a few weeks back and my anti virus thought it was malware. Could be that. I’ll white list all my unreal files to be safe. Thanks!
