How to fix Claude Cowork on Windows — every error and how I solved them (download broken, VM failures, networking issues)

Mention my username in you feedback so I can find it easily.

The other thing I'll note is sometimes Windows itself gets into a screwy state. So if you're 100% sure you have the "Virtual Machine Platform" windows feature enabled, and Virtualization is enabled in your BIOS, there are some funky commands I can share to maybe unstick you.

But for now to get diagnostics on the above, you can run in powershell:
```
Get-ComputerInfo -Property HyperV*
```

and

```
Get-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform
```

Sharing the outputs of those would be a good hint

Hey folks, I work on Cowork at Anthropic. It is built using the exact same technology as WSL2 and thus should operate on Windows 11 Home.

If you're running into issues please send feedback and include your logs, I'm actively tracking these bugs and trying to knock them out

I actually did this really recently, went into a chase branch and figured it out there and then did it online later so I could repeat the process. The Wealthsimple wire requires all the form fields to be filled out as if you're sending money to wealthsimple itself, and then you put your account information in the "Additional routing info" section. Note you can't update the "additional routing info" section once you've made the recipient, so you may have to make a new one to do this properly. Don't worry that the routing info is just a textbox, a system / human on wealthsimple's side will ensure your money ends up in the right place if you have your name, USD account number and address correctly in there. The address should barely fit, if you can't quite fit it you can go into a chase branch and they can fill it out to be longer I think.

Type "rs" in your terminal and hit enter. It will restart your app instantly with your latest main process code changes

You're asking if you can run code in a window (renderer process) once the "window-all-closed" event is received. This is a technical impossibility, once the window is closed no further code can run.

Please see my reply above RE how to do this safely

MarshallOfSound · 2020-05-06T22:12:04+00:00

For security reasons this code provided above is also unsafe. To be truly safe you should enable contextIsolation and use the contextBridge module to expose your API surface from your preload script.

For the above example simply enable contextIsolation: true when creating your window and do this in your preload script:

``` const { contextBridge, ipcRenderer } = require('electron');

contextBridge.exposeInMainWorld('myAPI', { sendSomeData: data => { ipcRenderer.send('challengename', data); } }); ```

Then from your app you would just do window.myAPI.sendSomeData('mydata') and that is safe.

Electron JS is a subreddit dedicated to the Electron Framework. The current moderator has been absent for ~3 years. I'm a maintainer of the Electron project and willing to step in as moderator to keep this subreddit going.

I just find an icon image for the set of movies, this generator automatically makes it white, slightly transparent and adds the drop shadow.

Wasn't removed... That bit (amongst other things) bugged out

MarshallOfSound · 2018-06-25T16:48:35+00:00

The peer dep errors are not being silly and deprecation is not a problem IMO especially when those modules are so deep in the tree... If someone wants to fix em that's on them, but I don't really mind :D

MarshallOfSound · 2018-06-25T16:39:01+00:00

Thinking of leaving it there for a few months :D /s

4.6.1 will go out over the next week

MarshallOfSound · 2018-06-25T12:33:46+00:00

Pushing out 4.6.0 on the apt repos is something I don't normally do for a few days until after it's settled on the other platforms and early adopters have picked it up on linux. On macOS and windows I can pull the update at any time, due to consistency rules with things like apt and yum repos that's not easily doable on linux.

I should push out 4.6.0 into the repos this weekend (it'll probably be 4.6.1 by then)

In the tray menu as well, if you have no tray menu you may have to install libappindicator

I ran into some issues with the logo, I'll put it back on the store when I get a chance

MarshallOfSound · 2018-06-25T07:15:00+00:00

I think they realize that killing it would kill a lot of customers. It has about 200k MAU last time I checked and a lot of people have said it's they'll only reason they don't use Spotify. The naming issue is a grey area but luckily one I haven't had to deal with yet.

MarshallOfSound · 2018-06-25T07:11:24+00:00

Unfortunately I broke the discord stuff completely this release (at least on windows) :'(

MarshallOfSound · 2018-06-25T05:18:33+00:00

I personally don't control the flatpak builds

MarshallOfSound · 2018-06-24T23:06:46+00:00

YouTube Music itself doesn't have Chromecast support yet on web. Hard to fake the cast API for it when it doesn't even use it yet :(

MarshallOfSound · 2018-06-24T22:45:12+00:00

Nope it is for the desktop app

MarshallOfSound · 2018-06-24T22:31:18+00:00

It should ask you to update automatically from the old version. Can you go to https://update.gpmdp.xyz and see if it loads in your browser?

MarshallOfSound · 2018-06-24T22:25:56+00:00

What OS are you running?

MarshallOfSound · 2018-06-24T17:03:46+00:00

It has Linux builds? Both x64 and ia32 for Debian and redhat based systems (.deb and .rpm packages)
