How to force install a Demo version of game you already own in Steam?
Is it possible to force install the Demo version of a game, for which you already have a full version in Steam?
The reason I want to install a demo is that I want to use it for tests. Like for example, comparing performance with different Vulkan implementations for AMD GPU. And the full game takes significant space on my SSD and I do not want to keep it.
When I go to the game page, and press "install demo", the installer still wants to install the full game (you can see it asks where to install and the required size is big for full version).
Best Answer
The workaround solution I found for now is to create a second steam account and install the demo using it.
But would be glad to hear if there are other methods.

Just go to your web browser [while] logged out and click on 'Download demo'. It will ask you to open Steam and it will download.
Solution found here. It's still a nuisance, but less so than using an alternative account.
Updates as I try some options:
I think the first prerequisite is that you have the full version uninstalled.
