DLLs not found with tweakscale

[Butterguy]

I am trying to play with some mods for the first time (I'm using forge) and when I launch it gives the showstopper warning and it says tweakscale did not find the required DLLs and that Scale.PartDB.18x is missing or one of its dependencies and I don't know how to fix this

Firstly, are you sure you have the dependencies installed, I think they are Module Manager, KSP Recall, and the TweakSacle Redistributable. There are also compatibility patches, which might be relevant if you are adding this to an already modded game, I think there is an all-in-one version called something like the "Uber Paket", which should cover all bases.

If that is all accounted for, and keeping in mind that I saw this error crop up recently, but only once, when reinstalling mods in different orders/stages (and I didn't actually have tweakscale installed at the time); I think you might be able to fix this by changing the order you install mod manager and any fix/compatibility mods you might be using (like KSP Community Fixes/Harmony/Patch Manager). Sorry I can't be more specific.

If that isn't a quick fix; given that some of the mods I mentioned, or similar ones, might patch or add new files, variations on this theme might also yield results. In order of troubleshooting efficacy (though not necessarily practicality), I would:

• Completely delete your KSP directory (backing up saves you might want to keep, the main config if you want to save current menu settings, and any zipped mod installation files that you really don't want to redownload), then reinstall KSP.
• Adding just TweakScale and it's dependencies to and unmodded game and confirming that the error is not logged any more.
• Adding Module Manager and other patches/fixes to an install with only Tweakscale (and dependencies) installed, and running the game once to generate any patches, and check the log.
• The above two steps but reversed.
• Keep searching the internet/TweakScale forum posts/github development page for any mentions of this issue, and try not to give up in exasperation.
• (Ideally after trying all the above) Report it as an issue on the development page/forum thread and hopefully get a solution or bug confirmation and fix.

I've heard people claim, quite a few times, that some errors are fine to ignore. However, without confirmation of this, the least recommended "solution", if you don't mind losing a game in progress, and the mod seems to be working, is; Hope the error isn't causing save corruption, and keep playing. (Backup a save from before you installed TweakScale).

Hope this helps, but at least I confirm I have seen this error crop up and go away, even if I can't actually tell you how or why.
