Alchemy is a Second Life compatible viewer striving to be at the forefront of stability, performance, and technological advancement in the open-source metaverse viewer field.
While installing to the newest Alchemy I noticed the uninstaller leaving behind a concerning amount of files and registry entries. Running the installer I confirmed the only prompt I got was the one below and no extra prompt to remove cache and settings(which is prompted for in FS)
Once the uninstaller completed I restarted my PC and confirmed the below is still intact. While some might seem harmless like some registry entries, its still very messy to leave these. But also leaving the cache intact leaves behind several GB of files on users PC.
From what I can tell everything in Appdata gets left behind.
C:\Users\username\AppData\Local\AlchemyNext
C:\Users\username\AppData\Roaming\AlchemyNext
Including the following registry entry locations (not all being directly related as some including detection entries by windows)
This is particular a bad issue if some say tries Alchemy but doesn't like it and uninstalls it. Unless they are tech savvy enough to know about appdata, many GB and registry entries will be left behind till they get a new PC or reinstall Windows.
Reproduction steps
Run uninstaller for Alchemy ether from Windows Apps & Features, or unins000.exe
Click Yes on 'Are you sure you want to completely remove Alchemy Beta and all of its components?'
Once uninstaller completes reboot PC
Verify the listed files and entries listed in report are still left behind
