[Qgis-user] Unable to load project

[Patrick Dunford]

The Windows version of Qgis allows you to run multiple versions on your 
computer side by side. I personally haven't used the Windows version for 
several years so I can't be sure if you will have any issues running 3.0 
alongside your current version. I run many of the editions I have in 
virtual machines. If your PC has 8 GB or more of memory, or if you have 
access to another computer that can run Linux, then you can try it out 
in a Linux virtual machine or physical computer environment without 
disturbing your current installation.
