Hi! I just realized that this application is from 2017, but I'm going to post this anyway!

Where is the Directory App installed?

I can't seem to find it. I've checked both my programs folders, my documents folder, AppData, ext, and I can't find hide nor tail of it. It also doesn't show up under the recently added section of the windows start menu. If I re-run the installer though, it correctly identifies that the program has already been installed and attempts a repair.

If you see this, thank you!

Hey!
No problem, I just double-checked from my end, it was a WPF app that I used the default install wizard for. In the installer, you're prompted to set the install location, which when running the installer was by default for me: Progam Files (x86) -> Pixcel Studios -> DirectorySetup.

Hope that helps! 

As a separate tip, a tool I use that I do still see infrequently recommended (and would definitely recommend myself) is 'Everything' by Void Tools (https://www.voidtools.com/) - it indexes your file system and then lets you search and filter files instantly, so you can much more easily find lost files by partial filename matching and file types without waiting 30,000 years for the built in windows explorer search to work and give unuseful results. In this case, could've searched "*.exe directory" and instantly found it! I find it very useful for relocating individual assets from specific projects or hard drives, or just old things I downloaded but don't remember the exact names, etc.
