Upgrade from AGT 2 to AGT 3 did not install VST3 plugins – Ample Sound Forum

Hi Ample Sound,
I just tried to upgrade my Taylor guitar from AGT_2_5_5 to AGT_3_7_0 but the installer did not install the AGT3 plugins. I installed the AGT 3 to the same folder as my AGT 2 (C:\Program Files\Ample Sound), and checked the box for VST3 plugins, but they did not install. Do I need to uninstall AGT 2 first? I’m afraid of losing my settings if I do that. Can I install AG3 to a different folder and keep them both? Any help will be greatly appreciated.
