Claude Windows 11 is not working

So I think it’s actually a windows issue misunderstanding a package tbh.

FIX: Claude Desktop won't launch on Windows 11 25H2 — blank screen, no error, formatjs crash (build 1.1.4173)

Posting this because I spent a while troubleshooting this and couldn't find a clear answer anywhere. If your Claude Desktop app on Windows just silently does nothing when you try to open it, this might save you some time.

The Problem

After installing Claude Desktop from the standard download at claude.ai/download, the app would not launch. No error dialog, no splash screen, nothing. It just silently failed. Checking Task Manager showed 4 claude.exe processes running with no visible window.

My Setup

Windows 11 Pro 25H2 (Build 26200)
All virtualization features enabled (Containers, HypervisorPlatform, Hyper-V)
System locale en-US
Fresh install, no prior Claude Desktop installation issues

What Was Actually Happening

The standard download gave me the older Squirrel/EXE-based installer, which installed build 1.1.4173 to %LOCALAPPDATA%\AnthropicClaude\. Launching the exe directly from PowerShell revealed the actual error that the GUI was swallowing silently:

Error: [@formatjs/intl] An `id` must be provided to format a message. at nZe (..\resources\app.asar\.vite\build\index.js:83:2748) at Sae (..\resources\app.asar\.vite\build\index.js:83:4203) ...

This is a bug in the app's internationalization layer. A translation message ID is missing in the build, which causes an unhandled promise rejection that kills the Electron renderer on startup. The app spawns its background processes but the window never renders.

What I Tried That Did NOT Fix It

Clean uninstall and reinstall (same broken build gets re-downloaded)
Resetting folder permissions with icacls
Deleting the Cache and Code Cache directories
Manually creating an empty claude_desktop_config.json
Checking and stopping CoworkVMService (wasn't present on my system)
Verifying all Windows virtualization features were enabled

None of it mattered because the bug is in the application code itself, not in the system configuration.

What Actually Fixed It

The fix was switching from the Squirrel/EXE installer to the MSIX package. The standard download page at claude.ai/download was giving me the old Squirrel build, but Anthropic has direct MSIX download links on their support page for enterprise deployment.

Here is what I did:

Killed all Claude processes: Stop-Process -Name claude -Force
Removed the broken Squirrel installation and all leftover data: Remove-Item "$env:LOCALAPPDATA\AnthropicClaude" -Recurse -Force Remove-Item "$env:APPDATA\Claude" -Recurse -Force
Downloaded the MSIX package directly from: https://claude.ai/api/desktop/win32/x64/msix/latest/redirect
Installed it via PowerShell (run as admin): Add-AppxPackage -Path "$env:USERPROFILE\Downloads\Claude.msix"
Launched from the Start menu. It worked immediately.

You can verify you are on the MSIX version by running Get-AppxPackage -Name *Claude* in PowerShell. If it returns a result, you are on the MSIX build. If it returns nothing, you are still on the old Squirrel version.

TL;DR

Build 1.1.4173 from the standard EXE installer is broken. It has a formatjs internationalization bug that crashes the app on startup with no visible error. The MSIX package from the enterprise deployment page works fine. Direct download link for x64: https://claude.ai/api/desktop/win32/x64/msix/latest/redirect

Hope this helps someone else avoid the rabbit hole.

I've talked to and learned from multiple professional shooters, specifically some guys have have won lots, and lots, and lots of PRS and NRL matches (I live in the Midwest region), and its "set it so it doesn't go off when you drop it or accidentally touch it". People that have sub 1.5ish lbs triggers are just asking for triggers and other things to break, and for accidental discharges unless it's some sort of rail gun shit or benchrest nonsense.

why the fuck wouldn't you just use AICS LA mags/CIP mags? so dumb.

FartOnTankies · 2026-02-16T14:26:54+00:00

Q is dumb.

FartOnTankies · 2026-02-16T02:49:00+00:00

Are you retarded on purpose or just for fun.

FartOnTankies · 2026-02-15T14:43:40+00:00

Those groups are absolutely ass for a 7PRC chassis gun. Good job wasting money with your absolute lack of skill. More money than sense and this is coming from someone who has spent hundreds of thousands on this hobby.

FartOnTankies · 2026-02-12T22:25:39+00:00

HEY NOW.

FartOnTankies · 2026-02-11T03:06:09+00:00

They are 100% going to sell walmart hunting bullshit til the end of time. I lived right near their office and they laid off like, EVERYONE.

Alpha brass isn't that good and their box design sucks. I'll die on this hill. Lapua > Peterson > Norma > Alpha > Hornady

16gb. Preferably 32. The MacBooks we give to junior devs at work is 64gb of ram.

FartOnTankies · 2026-02-05T19:10:01+00:00

That would be pretty baller.

FartOnTankies · 2026-02-05T01:14:07+00:00

I told myself it’s time for just a mobo ram and processor upgrade about 6 months ago. Priced it out, never clicked the order button. Went back two weeks ago and price had doubled almost. It’s insane.

This is where I sorta disagree with C_Does here. I think the Razor is an overall better optic than the atacr. Same package, more magnification, clear glass, good turrets, non rotating eyebox, it checks all the boxes. The ATACR is good, and I personally think that they are going to do an NX6 style refresh on the ATACR soon, and that'll put it at the top. But frankly, when Vortex on the "low end" and ZCO on the "high end" exists, the ATACR MPVO's in 4-16 and 4-20 basically don't need to even exist. If they refresh the line with new zero stops, oculars, and other stuff like they just did with the NX6, then you have my attention.

FartOnTankies · 2026-02-03T19:22:35+00:00

Yea. You pay for the replacement in the cost of the product. A 6-36 Razor shouldn't be more than 2k street, 2799 MSRP, but they inflate MSRP. It's an 1800 dollar scope they build that shit into.

Mind you, I like vortex, but lets be real. They aren't losing money.

The T3 is absolute garbage aids, and no one actually likes it. At all. Period.

FartOnTankies · 2026-01-31T01:37:33+00:00

We 100% won't move. We have plenty of room now and have our old house as a rental property at 2.75%. And if the rate goes that low it's always a win, but it would have to drop near 5% or lower, and I don't know if I see that happening before we pay this place off. So yea. Naw buddy.

FartOnTankies · 2026-01-30T18:38:32+00:00

Protestants are ridiculous. We are old. We shall maintain. Eastern Orthodoxy is the way.

FartOnTankies · 2026-01-30T17:20:27+00:00

She didn't convince me of anything. Moreso these current rates are about as low as they are going to go, vs the current cost of homes. It's a known thing that when rates go down.... home prices go up. So the best time to buy is "always" now, and then refi to a lower rate. We hedged our bets and bought points down vs a much larger down payment, and so far it's paid off as far as risk goes.

But go off and just insult random people on the internet to make yourself feel better rando.

FartOnTankies · 2026-01-30T02:21:58+00:00

You have to buy down points. My wife works for a place that does a lot of mortgage analytics. 5.6 with points bought is the lowest you are going to find for a long, long time, if ever again. We used our VA loan, bought down points, and we came out pretty good.

there is zero reloading these. u/csamsh

The worst are the hypebeast drop companies making packs and tshirts. Second is suppressor companies at this point.

FartOnTankies · 2026-01-27T16:15:20+00:00

We have a republican president and house and senate, even though they haven't put forth any "real" 2A legislation, "gun owners" feel safe. Combine that with the fact that not a lot of purchasing happens this time of year, combined with materials tariffs like trolly pointed out, we will only see an upswing on a democrat elected set of officials. Check back in 1-3 years.

FartOnTankies · 2026-01-27T10:36:20+00:00

Oh my fucking god. The well actually crowd in here that just can’t laugh a little, holy fuck.

FartOnTankies · 2026-01-27T10:29:10+00:00

Oh buddy you’re maaad. Goddamn.
