Unable to install new model .ckpt

When I try to install any .ckpt model I get an error that tells me it is trying to unpack a zip.
I tried zipping a model for it to unzip, but the file selection only allows .ckpt files.

This is the error of an example file.

Error Traceback (most recent call last):
