Right now, if you install 2.0 with the default settings, only Antigravity 2.0 will launch, completely locking you out of the IDE.
The reason is due to how the Electron framework handles deployments. Electron loads resources based on directory location. Because the 2.0 update dumps its files into the exact same folder as the IDE, the newly added 2.0 app.asar completely hijacks the original Antigravity IDE executable.
1. How to fix the launcher (Toggle between IDE and 2.0)
Open PowerShell and run this to disable 2.0 and force the IDE to launch:
PowerShell
cd "$env:LOCALAPPDATA\Programs\Antigravity\resources"
Rename-Item app.asar app.asar.bak
If you ever want to switch back to using 2.0 only, run this:
PowerShell
cd "$env:LOCALAPPDATA\Programs\Antigravity\resources"
Rename-Item app.asar.bak app.asar
2. How to restore your missing settings, keymaps, and extensions
If you restore the IDE using the trick above, it will look like all your themes, keymaps, and extensions were wiped.
Here is why: Antigravity is built on VS Code, meaning it generates configuration folders based on the product name.
Original IDE (1.x) & 2.0 â Product name: âAntigravityâ
Settings: ...\Roaming\Antigravity\
Extensions: ...\.antigravity\
(All your actual settings since Dec 2025 are trapped here)
Restored IDE â Product name: âAntigravity IDEâ
Settings: ...\Roaming\Antigravity IDE\(Empty new folder)
Extensions: ...\.antigravity-ide\(Empty new folder)
The Fix:
Go to C:\Users\<YourUsername>\AppData\Roaming. Copy the contents of the Antigravity folder and paste them into the Antigravity IDE folder. This restores your settings and keymaps.
Go to C:\Users\<YourUsername>\. Copy the contents of the .antigravity folder and overwrite the contents in .antigravity-ide. This restores your extensions.
Getting a Windows path depth limit error?
If Windows blocks you from copying extensions due to path length limits, open an Administrator CMD and use a symlink (mklink) instead:
Google made a rookie Electron deployment mistake. Prioritizing app.asar is normal Electron behavior, but deploying a new product into the exact same folder as the old one is ridiculous.
The 2.0 update overwrites the IDE in the same installation path but changes the product name, which splits the config folders.
They did all this without writing any migration logic to move your settings over, effectively wiping your setup.
I copy-pasted your entire post to Antigravity. Gemini Flash 3.5 then proceeded to build me an UI Toggler (see screenshot). It works my extensions and settings were restored as well.
Thatâs quite brilliant! My sincere thanks for sharing this insight. I embarked on a similar endeavor, crafting a toggler with Electron, yet I consistently encounter an error indicating that the âapp.asarâ file is either busy or currently in use. Could you please divulge the specific toggler command you employed? Alternatively, would it be possible to share the application directly, perhaps via GitHub or another hosting platform? My gratitude.
gemini gave me below script based on above problem statement , save this file as Repair-Antigravity.ps1 and run powershell under admin mode and this is for windows
I basically copied the entire post by OP and pasted it to Gemini in the new Antigravity. I asked it to create a Toggler for switching between classic IDE and the new v2 interface.
Your Antigravity must be closed while switching. I did this on my work laptop, uploading is blocked so I canât share the file. I canât even send it to my personal email because that will get me in trouble with Security. But see my reply below. Hope it works for you.
Well, for anyone who wants a quick fix that enables both 2.0 & IDE at the same time easily, here is an automated installer (that needs node in path). there are some other features/ideas too, but they might not all be working. The important part tho, the IDE install (which is silent) should work fine (as long as the download link stays unchanged).
Enjoy! (it works!! (kind of!!!))
Edit: I tried on my other PC, it did work, but it was a bit harder smhsmh. classic.
for the brave still: launch the .bat first, then look in Task Manager to see when Antigravity IDE Setup/Installer finishes (the completion bar goes from 0% to 100% directly in the UI (if it updates at all)). It might take quite some time, Defender myb slowing down the installation (not sure why, myb unsigned/unverified or smth? for the bravest, you can keep Defender off while it installs, but itâs gonna be fine either way unless youâre on a pepeCPU (like me)). Anyways, IF the UI bar doesnât update to 100% by itself after the installer finishes/closes from the Task Manager, you can manually go to âAppdata/Local/Programs/Antigravity IDEâ and you should see âAntigravity IDE.exeâ. Open it, and the localhost UI should update/recognize the installation & enable access to other settings. gudjub warrior, the sjuggle ends here
Having to resort to these hacks to fix a bug that OVERWRITES your IDE with another separate product is the most shameful thing Iâve seen in years. Seriously; how can a company like Google allow this to happen, and how is it possible that they havenât provided and official solution yet? What a shame.
Oddly, I am not to concerned about the new Agent conversation view, however, I do want the IDE available as well.
I can launch both 2.0 and 1.0. In the old IDE, it tries to update, even when I have 2.0 installed. I can cancel it, but it comes up from time to time while the old IDE is open.
The odd thing I am seeing: 2.0 doesnât inherit anything I made in the old IDE. So it looks like workflows, global agent rules, project rules, are all restructured and replaced with the settings for skills.
Also, I noticed a lot less projects visible in the 2.0 interface. Hopefully Google fixes some of this.
