cannot install bootstrap v5.3.1

I am trying to install the bootstrap library on my DNN v9.11.2 site, when I do the drag and drop on the extensions > install extension section the installation fails

Message Error:

An unknown error has occured. Please check your installation zip file and try again.
Common issues with bad installation files:
Zip file size is too large, check your IIS settings for max upload file size.
Missing resources in the zip file.
Invalid files in the package.
File extension is not .zip.
Check that you are logged in.

Is this the file you're uploading? https://github.com/EngageSoftware/DNN-JavaScript-Libraries/releases/download/bootstrap_5.3.1/bootstrap_5.3.1.zip

That could happen if you accidentally download the repository source instead of the package. You can also open your browser developer tools and look on the network tab to see if the upload request/response has any other details about the error.

Hope it helps!
