After the last update three days ago in a miktex version using the miktex next repository the newer updates dont work (see the error message and log file), but these dlls are in the asked directory.
If I try to work with latex/xetech/pdflatex (from winedt) it brings the error message that dlls are missing, especially MiKTeX209-next-popt.dll, next-libressl-crypto.dll and next-expat.dll. These dlls are missing in the directory if I control with explorer.
I had problems after an update of miktex next thursday evening too. A lot of dll where missing and the mpm-GUI didn't start anymore. On friday I could repair it by first creating a list of the packages with
and then installing all the missing miktex packages (starting with lzma, zzip etc) one by one with
Now it works fine.
Imho the problem was due to a timing problem in the repository: On thursday quite a number of packages were removed but the needed replacements appeared in the repository only on friday morning.
Thanks Ulrike, it was a little bit tricky, but it works now. But now I have the same problem with luatex like you ... Regards, Matthias
Because the missing miktex209-next-jpeg/png.dll problem still exist I installed miktex new. After switching to the experimental packages (I had to do to use luatex) the same problem occurs
The package manager claims that miktex209-next-png.dll, miktex209-next-jpeg.dll and miktex209-next-gd.dll are in the packages miktex-png-bin, miktex-jpeg-bin, miktex-gd-bin and the 64bit versions in miktex-png-bin-x64, miktex-jpeg-bin-x64, miktex-gd-bin-x64. All three .dll are in all three packages, so installing one of the packages should be enough. I have the dll in my bin folder and I seemed to have installed the png package as last package so I'm probably using the versions from this one.
I think, this solution is not applicable to "MiKTeX209-pdftex.dll", is it? - After an update today, this DLL is not found available any more on my system.
