Can't launch Packaged game (can't find descriptor file)

I’ve searched the forums but haven’t found a solution to my particular problem:

I package my game and can launch it find on my computer. When using a coworker’s computer, however, I get the error “Failed to launch…can’t find descriptor file 'projectname.uproject”

I’ve tried installing the vredist_x64/85 distributables for visual studio, but this doesn’t fix the issue.

Any help appreciated!

I am packaging the game for Windows…

The error is the same regardless of project:


I should add that I have U4 Editor installed, my coworker does not.

I solved my issue: turns out it was unrelated to Unreal and had to do with accessing the project over our network.
