Install error running Setup.exe with 1.7.6 only

[DaneVinson]

As of 1.7.6 running Setup.exe throws the following error at the end.

The application runs as expected after the error and the app's directory and file structure (in AppData\local) look correct. If I uninstall, roll back my Squirrel version to 1.7.5, releasify again and run setup again I no longer get the error. I'm attaching a SquirrelSetup.log file with has two setups in it. The first using 1.7.6 (error) and the second using 1.7.5. I don't see any differences. There are a few errors listed but they exist in both runs (and are what I've typically seen in all Squirrel installs in the past). I'm not sure how to debug this one.

I'm experiencing this as well, and I only noticed because I had an older solution to test Squirrel out with lying around, and this solution still used 1.7.5.

For reference, I've attached logs for both the failing 1.7.6 installation and the working 1.7.5 installation. As @DaneVinson points out, they both contain the same Exceptions, though everything I've read about these indicates they're "only" warnings. The logs seem to match what Dane's got pretty well.

I'm also experiencing this with 1.7.6

On a windows 8 machine that I've been experimenting with I get an extra error report that hints at an ObjectDisposedException. The pop-up isn't very enlightening, unfortunately.
