Getting "Writing File" Error and Javascript Error - Windows

The main hub downloads just fine but when I try to download the labs themselves I get one of these two pop-ups.

Any idea what’s going on and how I can fix it?

Error Writing File

Oh boy- those look like residues of what happens when antivirus software disables our program piece by piece. Maybe it put some things into quarantine.
So you are going to need to create exceptions for the folders where our program is and then try running it again. If that doesn’t solve it, you’ll probably need to uninstall the programs and then download the software again.
Please feel free to email us at if you need any further assistance.

I’ll try that - thank you!
