Sure thing MichaelS, there is the 'easy' way, and the 'what the !@#$ were they thinking' way. I'll cover the 'easy' way here for you
This does depend somewhat on how you installed Lc. I always install for me only, and so can do this with just my own user priviledges. If you installed "For everyone", then you will need to do this under sudo or root priviledges.
You simply need to navigate to the Lc installed folder, and click on
setup.x86_64. If you installed for you only, this will (likely) be located in your home folder at this path:
~/.runrev/components/livecodecommunity-9.6.0-dp-4.x86_64/setup.x86_64
{ Note the '.' in front of the runrev folder name. This is a hidden folder in your home directory, so make sure hidden folders are visible in your file manager either through the menu, or by using [Ctrl + h].
Also Note that 'setup.x86_64' applies to Lc from 7.1.4 forward to current, before that, it was just setup.x86.}
If you installed 'For everyone', on the other hand, you would navigate to your opt/runrev folder as sudo or root and run setup.x86_64.
Of course, if you installed it to a custom location, you would navigate there and uninstall it.
That is it.
