Kodi upgrade

Not within Kodi... you can download from them and go right over the top of previous BUT sumtimes it won't work, and you have to do a fresh install. Go to Kodi and try ..we are all Beta Testers here. :)
 
I had to uninstall my Kodi 16.1 before I could install 17.6 which I did. All my personal apps are not showing? Message says Library empty add media source to populate my add ons??????
What am I not doing or are my personal addons gone?

Normally you just install the newer version without uninstalling the old version. If you didn't copy your userdata folder somewhere for safekeeping, I'm afraid you're out of luck and have to start from scratch an reinstall everything and any library that you had. Bummer. It's a good idea to always have a backup if you have stuff you care about. When you reinstall everything, copy the userdata directory to a thumb drive or a network location.
