Installation & Update Issues
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 Add-on installation pollutes the Application data folder with scripts and libraries from older blender versions. This can easily make it impossible to install another Add-on. We make sure that our Add-ons 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, such as:
- 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 Add-on that you have installed is no longer visible and you need to install them again. However you can use the hidden subfolder ( 2.82_hide in my example) to recreate your installation. Although in most cases it seems easier to install all of your Add-ons again.
