DLL load failed: %1 is not a valid Win32 application
This happens on Windows when your Blender Application Data folder is corrupted. We never found a good reason for when this happens, but it does happen.
Clean up your Application Data. You find the data here:
Sometimes another Addon installation pollutes the Application data folder with scripts and libraries from older blender versions. This can easily make it impossible to install another Addon. We ensure that our Addons never creates such sort of pollution. And here is how you can get out of this issue:
- Locate the Blender Application data folder (see above)
- within the folder locate the subfolder that is named like your Blender release, for example:
- rename this folder to something like
Note: The name is not important, use whatever is convenient for you. You even can delete the folder if you like, but see below!
- Now restart Blender
This will cleanup your application data folder. But take care! This resets blender to its Factory settings. Any other Addon that you have installed is no longer visible and you need to install them again. However you can use the hidden subfolder ( 2.77_hide in my example) to recreate your installation. Although in most cases it seems easier to install all of your Addons again.
