Error on building branch 5005

[delphirules]

On Win 10, i'm trying to build the branch 5005 , but after some time got the error below. I could build the previous branch without porblems, but this time i tried three times and the same error occurs. Please help , thank you very much !

Here is my BAT file used to build :

del /f /s /q chromium_git 1>nul
rmdir /s /q chromium_git
set GN_DEFINES=is_official_build=true use_thin_lto=false proprietary_codecs=true ffmpeg_branding=Chrome
set GYP_MSVS_VERSION=2019
set CEF_ARCHIVE_FORMAT=tar.bz2
python3 automate\automate-git.py --download-dir=e:\code\chromium_git --branch=5005 --minimal-distrib --client-distrib --force-clean

Abd below is attached the last lines generated by the commands above :

Branch 5005 requires the 10.0.20348 Windows SDK. See https://bitbucket.org/chromiumembedded/ ... -supported

Thank you for the info, will install the new SDK and try again tonight

[delphirules]

I updated the SDK, and now the errors changed. Here are the last lines of the log , please help

Did you install all required Visual Studio components? https://chromium.googlesource.com/chrom ... ual-Studio

I suppose yes as i could build the previous branch. Do i need to uninstall VS 2019 and install it again because i changed the SDK ?

[magreenblatt]

That shouldn’t be necessary. Do these DLLs exist?

Tried again today but still, same error

I've upload the complete log file at https://we.tl/t-nX9WmlzhXQ

But here are the last lines ; any help is very appreciated as i need to build the binaries for an application that use CEF. Thanks in advance !
