Could not load file or assembly System.Data or one of its dependencies

[jeffgiffgaff]

***I'm using Windows 10 When I attempt to open the ckan.exe (and access the GUI) which I have in my KSP directory, CMD is opened and this is printed out:

Unhandled Exception: Autofac.Core.DependencyResolutionException: An exception was thrown while activating CKAN.Configuration.JsonConfiguration. ---> Autofac.Core.DependencyResolutionException: An exception was thrown while invoking the constructor 'Void .ctor(System.String)' on type 'JsonConfiguration'. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

I've attempted to use cd (ckan.exe directory) and subsequently ckan.exe help and the help commands are listed out as such:

You are using CKAN version v1.30.4

but every time I try to run one of these commands it gives me the same unhandled exception stuff. I've attempted reinstalling CKAN and KSP several times as clean as I know how but this always happens. Note that I am not at all good with coding I don't know much about this stuff so you'll have to dumb it down for me.

Thank you to anyone who can help.

System.IO.FileNotFoundException: Could not load file or assembly 'System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

This sounds like a issue with your .NET Framework installation. Try reinstalling it from here

I downloaded and ran it but it said I had the latest version, and that I don't need an update. I've looked through all the other issues similar to mine I could find but nothing from those has worked. I'm really not quite sure what I should do.

Maybe you already have a more recent version; I was able to re-install 4.8:

https://dotnet.microsoft.com/en-us/download/dotnet-framework

(My re-installation of 4.8 may have been an install rather than a re-install; I think I had the SDK stuff before:

But either way, the point is to try to repair your install so that System.Data can be loaded.)

So both the 4.5 and 4.8 installations will just say this. Also apologies again but I'm not very technologically literate so what do you mean by the System.Data? is that a windows file or Kerbal Space program one? Is that the name for GameData on a different System? Also- I forgot to mention but I am on Windows 10.

[HebaruSan]

System.Data is part of the .NET Framework, the thing we're trying to help you reinstall.

Try this:

1. Start → Programs and Features
2. Find "Microsoft .NET Framework 4.8"
3. Right click it and choose "Uninstall/Change"
4. Use the repair option:

[jeffgiffgaff]

It doesn't show up when I search for it which is quite strange. I go to programs and features and search but its not there which is just very confusing when its already telling me It's installed when I try to instasll .NET? Again, thank you so much for helping though

[jeffgiffgaff]

does anyone know what i should do :(

[HebaruSan]

Keep trying to repair your .NET install. If you really can't find any way to fix it, then we're not going to be able to do much for you.

Okay thank you I understand. I've looked at some registry and it appears I don't actually have the .NET framework installed so I'm going to try and get that properly installed, and I will keep you updated if that's alright with you. Thanks again!!

[jeffgiffgaff]

It turns out Windows 10 doesn't show the .NET framework in the programs and features, but I've managed to find the registry and I'm pretty sure its installed. It's all very confusing. I've restored some CKAN folder I deleted a while ago when I was trying to get it to work by reinstalling but which I haven't seen until now? I'm so confused I really just want to use mods there has to be a fix. I've ran a .NET fix tool for windows 10 and it hasn't done anything I still am just getting the unhandled exception. Please help me.

[jeffgiffgaff]

Someone pls help me

[jeffgiffgaff]

According to this website, Microsoft .NET 4.0 is part of the Windows 8 Operating System, thus cannot be accessed from programs and features, subsequently making it unable to be edited or deleted. I am running on Windows 10, and by looking at regedit I can see I have .NET 4.8 installed. I don't think there's much I can do in the way of "repairing" the .NET installation from what I can tell. I very may likely be wrong as I'm not very good at this stuff. What should I do at this point? Why does my CKAN not work? Is anyone else having this issue? Please someone help I really want to play some modded ksp.

[HebaruSan]

No, no one else is having this issue. I suppose you could try reinstalling Windows.

[jeffgiffgaff]

No, no one else is having this issue. I suppose you could try reinstalling Windows.

What are the consequences of this, and is it safe?

[HebaruSan]

What are the consequences of this, and is it safe?

Reinstalling Windows resets your whole computer to how it was when you first got it. You would need to back up any data that you didn't want to lose to an external location. I would never say it's completely safe, but if you are completely unable to repair your .NET install, then I don't know what else you could try.
