ReSharper 2016.3 Installation Exceptions

I'm getting a ton of ZIP exceptions when trying to install the latest version of R# Ultimate, which is preventing the install from completing:

Furthermore, the installer uninstalled the previous version of R#, which is leaving me a bit stranded.  Are there any workarounds available to get R# installed successfully?
