Steps to Reproduce

1. Launch Unity
2. Install Github for Unity

I expected this to install without any errors that could not be cleared easily.

Actual behavior: hard stop error that will not clear

Reproduces how often: Always

Thanks for reporting this. We can work around it soon.

@trilobyteme While we're figuring out how to make this not happen, you can delete one of the copies of the assembly and things should work well - only one of them needs to be loaded in the process for things to work.

Hey @trilobyteme sorry this has taken so long to get to.
We have an official fix coming soon. It will be fixed along with #908.

Testing:

1. install our extension and that app from the store
2. delete octorun from your appdata folder
3. hit play and stop
