I have a skin to show GPU temperature which was working fine, but I updated to the latest version of Rainmeter: 4.5.13.3663 (64-bit) and now I am getting the error:
Plugin: Unable to load "MSIAfterburner.dll" (error 126)
It also does not show up under the Plugins tab in About Rainmeter
I know I can still use the Afterburner app, but where's the fun in that?
This error usually indicates a missing dependency for the plug-in. It's nothing to do with your skin, or Rainmeter. I don't know what that MSIAfterburner.dll requires, but most plugins that throw this error need either the Visual C++ runtime DLLs or the .NET Framework.
Also, make sure you have the latest .NET Framework installed; that is another dependency. You can get that here: Download .NET Framework 4.8.1. Versions are backward compatible, so if you have the latest, it should work with apps that use older versions.
Finally, before you install anything, try a reboot (or uninstall, reboot, install). Sometimes it can help.
If I'd thought about it sooner, I would've rolled back to a previous version of Rainmeter and that would've shown me it had nothing to do with Rainmeter or the skin. It also would've saved me asking a stupid question!
Anyway, just for reference, first I updated the .NET Framework as I had version 4.6.2. Restarted and the skin started working. I guess another quirk of Windows. Lol. But weird that it says that version 4.6.2 is still installed, but the 4.8.1 installer says it's already installed. A bit weird, but everything is ticking along nicely so I'm not going to start fiddling with things now.
Thanks again for your suggestions. I do normally do a lot more research, but I think my brain was switched off earelier.
