Hello, since me last “up” one hour ago, Plots doesnot work anymore (on my Windows 10 machine) because FFMPEG seems broken

But the artifact is there, and also the file “avcodec-58.dll” - it just seems not to be recognized as a dll file ?

What can I do to have Plots working again ?  
thanks for help,

Uh, no. I edited Manifest.toml

```julia
[[FFMPEG_jll]]
deps = ["Bzip2_jll", "FreeType2_jll", "FriBidi_jll", "LAME_jll", "LibVPX_jll", "Libdl", "Ogg_jll", "OpenSSL_jll", "Opus_jll", "Pkg", "Zlib_jll", "libass_jll", "libfdk_aac_jll", "libvorbis_jll", "x264_jll", "x265_jll"]
git-tree-sha1 = "13a934b9e74a8722bf1786c989de346a9602e695"
uuid = "b22a6f82-2f65-5046-a5b2-351ab43fb4e5"
version = "4.3.1+2"

```

and then `]instantiate`.

Can you please do the following:

```julia

Dear @jaakkor2, thank you for the answer - its works !

Just for the record, for others reading this post, the “Manifest.toml” to edit is that one of the project where I am trying to do the “using Plots”, so it case of not specified (no --project option), it is

```julia
"C:\Users\yourlogin\.julia\environments\v1.5/Manifest.jl" 

```

Thanks again! I mark your answer as solution, awaiting more permanent fix as @giordano said in

No, sorry, it doesn’t help because I need the output of the command _after_ you get the error, as I wrote just above

~~`FFMPEG_jll v4.3.1+2` is not, and it works.

`FFMPEG_jll v4.3.1+2` and `FFMPEG_jll v4.3.1+3` use _exactly_ the same tarballs, they haven’t changed.

Just updating the registry should now automatically bring you a working version of `FFMPEG_jll` (`v4.3.1+2`), but the root problem is still unclear.

Most kind thanks for repairing the registry/update system. I understand you still do not know what was the initial problem. What could I do to help get better info? (I have kept my specially tailored « .Julia » folder for tests, just in case …)
