Antigravity 2.0 installer breaks existing Antigravity IDEs

If you had Antigravity IDE installed before yesterday's 2.0 release, both products now live in the same directory and only one of them actually runs. Double-clicking Antigravity IDE.exe launches 2.0.

Electron exes load resources/app.asar first, then resources/app/, from the same folder as the exe. The exe name has no effect on this lookup. The 2.0 installer dropped app.asar (2.0 code) next to the IDE's app/ folder, and the asar wins — so both Antigravity IDE.exe and Antigravity.exe end up loading 2.0. if you window, Turn on the powershell

Workaround: cd "$env:LOCALAPPDATA\Programs\Antigravity\resources" Rename-Item app.asar app.asar.bak

Antigravity IDE.exe then falls back to the IDE's app/ folder and launches the real IDE 1.107.0. Rename back to restore 2.0.

Caveat: only one at a time. With app.asar renamed aside, Antigravity.exe also falls back to the IDE folder. Permanent fix is to uninstall both and reinstall to separate directories — the installer is Inno Setup (unins000.exe), so /DIR="..." should work. Not an Electron bug. Location-based loading is documented behavior. This is a packaging mistake in Google's 2.0 installer assuming two separate Electron products can share an install directory.
