Guest Mode Not Possible when Sharing Steam Library

Describe the Bug
I share my steam library with my wife. She downloade dthe guest edition of Talespire today, but is unable to launch it, as my full edition overwrites her installed version. When I am running Talespire, she is locked out from launching entirely.

To Reproduce

• Share a library (A) with the full version of Talespire to a person who doesn’t have Talespire (B).

• Have person B download Talespire guest edition.

• Person B will not be able to run guest edition, or any edition if Person A is running Talespire.
