Clean and reinstall process - HebaruSan/CKAN GitHub Wiki

If you have installed all your mods through CKAN, it is a quick and painless process to completely re-create your modded KSP installation. This will clean up most CKAN errors you may be experiencing.

Phase 1 - Save your installed mods

If your registry got corrupted or there's another reason you can no longer start CKAN, skip this phase.

Open the CKAN GUI client
Click File → Export modpack...
Click Export
Browse to a location in the save dialog
Type a filename for your mod list
Click the Save button
Close the CKAN client

Phase 2 - Clear out your KSP installation

Open your operating system's file manager/explorer program
Go to your KSP game folder (directory)
Copy the "CKAN" folder to "CKAN-backup"
Copy your "GameData" folder to "GameData-backup"
Copy your "Ships" folder to "Ships-backup"
Open the CKAN GUI client (again, only if you are still able to)
Uninstall all mods
Close the CKAN client
Open the "CKAN" folder
Select all files other than the "history" and "downloads" folder and the "installed-<instance-name>.ckan".
Delete the selected files
Return to KSP game folder
Open your "GameData" folder
Select all contents, then find the "Squad" and "SquadExpansion" (if present) folders/directories and un-select them
Delete the selected files & folders

At the end of this process you should have a "CKAN" folder containing a "downloads" folder which contains all your cached downloads, and a "GameData" folder containing just the original "Squad" folder with all its contents as installed with the game.

Remove modded ships

If you have Steam:

Return to KSP game folder
Delete your "Ships" folder
Open Steam
Right click on KSP
Properties...
Local Files tab
Verify integrity of game files...

This will restore the stock crafts only to your Ships folder.

If you don't have Steam:

Return to KSP game folder
Open your Ships folder
In the SPH, VAB, @thumbs/SPH, and @thumbs/VAB folders, delete all files for non-stock craft.

Stock craft files as of this writing (these are the ones you should NOT delete!):

Phase 3 - Reinstall your mods

Open the CKAN client
Select the compatible KSP versions as before
Click on "Refresh" to get an up to date list of mod releases
Click on the File menu, then select Install from .ckan...
If you exported your mods in Phase 1, select that .ckan file. If not, select the "installed-<instance-name>.ckan" file or any older backup file in the "history" folder
Click on Open
Click on Continue

If any of your mods were old versions, they will be downloaded and the new versions will be installed, while all other mods should be installed from cache.

Phase 4 - Tidy up

If all your mods are installed successfully and you are no longer experiencing errors, perform the following steps:

Return to your operating system's file manager/explorer program
Delete the "CKAN-backup", "Ships-backup", and "GameData-backup" folders

If instead, things are now worse than they were before, perform the following steps before continuing your troubleshooting:

Return to your operating system's file manager/explorer program
Delete the "CKAN" and "GameData" Folders
Rename the "CKAN-backup" folder to "CKAN"
Rename the "GameData-backup" folder to "GameData"
Rename the "Ships-backup" folder to "Ships"
