Read the topic. I double checked, as you see it I have 4.8 as said in the topic. I checked regedit too for the version. I also can run other .net framework 4.6 required apps like pkNX. was using PkHex until yesterday.

+ I opened pkhex before, I am sure its the same version as before.

Currently installed "classic" .NET Versions in the system: 2.0.50727.4927 Service Pack 2 3.0.30729.4926 Service Pack 2 3.5.30729.4926 Service Pack 1 4.0.0.0 4.8.04084 I have .Net 4.8, don't have the pkhex.core.dll in the same folder with .exe. .net checked with https://github.com/jmalarcon/DotNetVersions. which can be found in https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed I get this error message.
