Unable to deploy installer packages with spaces in the name using Casper 9.7 and HTTPS repo

I installed Casper 9.7 on a test server with an HTTPS file repo tonight and tested installing various installer packages via Self Service.

Most of the installations worked, but I had several failures. In testing, I was able to narrow it down to packages that had spaces in their names. When I renamed the packages to use underscores in place of spaces, the installations of the previous failing packages began working.

Here's the logs from a failed and successful install:
