Installation
This is what gets installed where you use Claude. It does nothing on its own: it is the bridge between Claude and the agent running on the other machine. The agent, golem.exe, is another file and has its own page: server kit.
Download
Windows · No administrator · Direct download, no account: without a license it starts in evaluation mode. The license, once you buy it, is downloaded from your portal: for that, create an account.
Golem is digitally signed
Since 1.1.3, golem.exe, golem-client.exe and the installer carry a publisher signature in the name of Irwin Alfredo Rodriguez Gimenez, with a timestamp. To see it: right-click the file → Properties → Digital Signatures, or run Get-AuthenticodeSignature in PowerShell, which must say Valid.
- SmartScreen: the certificate is new and Windows may still warn for a while. If “Windows protected your PC” appears, click More info: it must say Publisher: Irwin Alfredo Rodriguez Gimenez. If it does, Run anyway; if it says “Unknown publisher”, that file is not ours: do not run it.
- Remote administration tools: some antivirus products flag remote administration programs such as Golem by category, with nothing wrong in the file. If yours does, add the exclusion only after checking that the SHA-256 matches the one published below.
Before you install
The Golem installer is signed, but the certificate is new and Windows may still warn you the first time you run it. Here is what you will see, how to continue, and how to check for yourself that the file you downloaded is exactly the one we published.
The SmartScreen warning
If a blue window saying “Windows protected your PC” appears when you run it, click “More info” and look at the publisher: it must be Irwin Alfredo Rodriguez Gimenez. The warning does not mean there is anything wrong with the file: it means Windows has not yet seen enough downloads with this certificate to recognize it.
- Click More info.
- Click Run anyway.
Before that second click, check the hash: that is how you know what you are about to run is ours and not an altered copy.
If your antivirus stops it
Some antivirus products quarantine installers they rarely see. If that happens, add an exclusion for the installation folder, %LOCALAPPDATA%\Golem, and run it again.
If the antivirus belongs to your company and you cannot change its rules, give the SHA-256 below to whoever administers it: that is what they need to clear the file.
Check what you downloaded
These are the details of the current version, for the client installer and the server kit. Each hash is computed on the file exactly as it downloads:
| File | Version | Published | Size | SHA-256 |
|---|---|---|---|---|
Golem-Client-Setup-1.6.0.exe | 1.6.0 | 15 Oct 2026 | 30.4 MB | 88951E5DD1DD0CB862F865E54746E2B9A5F5ABBF604B2F08193610A83D789485 |
Golem-Server-1.6.0.zip | 1.6.0 | 15 Oct 2026 | 57.8 MB | 30035DEF0AE5BB7A37C68CEF061838912324DF5F21B7EE845C7EB6B8AE989E67 |
To check it, open PowerShell in your downloads folder and run:
Get-FileHash -Algorithm SHA256 "$HOME\Downloads\Golem-Client-Setup-1.6.0.exe"If the value matches the table, the file is ours and intact. If it does not match, do not run it: download it again and, if it still does not match, write to soporte@irwinrodriguez.dev.
Hashes are measured again for every published version. If you downloaded an earlier version, its hash will not necessarily match this table.
What the installer does
Double-click Golem-Client-Setup-1.6.0.exe and Next. It does not ask for administrator, does not ask for a folder and does not ask anything else.
It leaves one thing, golem-client.exe, in %LOCALAPPDATA%\Golem\, and registers the MCP server golem in:
- Claude Desktop, in its
claude_desktop_config.json; - Claude Code, at user scope.
Whatever you already had registered is left alone. The golem entry is added (or updated) and nothing else. Uninstalling removes that one, and only that one.
Checking the installation
Close Claude completely and open it again, so it reads the new configuration. The golem_* tools must show up. If they do not, check that %LOCALAPPDATA%\Golem\golem-client.exe exists: if it is not there, the antivirus took it (what to do is above, under “Before you install”).
Your machine ID
The license is bound to the technician's machine, so the checkout asks for its ID. The installer says it when it finishes, and you can get it again whenever you want:
%LOCALAPPDATA%\Golem\golem-client.exe --machine-idIt comes out shaped like 4F2A-91C7-0BD3-56E8. It does not matter how you type it (with hyphens or without, upper or lower case): it is normalized when checked.
It changes if you reinstall Windows or rename the machine. Changing disk, RAM or network card does not change it. If you have to move it, write to soporte@irwinrodriguez.dev and it gets reissued.
Installing your license
- Download the file from your license detail page in the portal. It already downloads with its name:
golem.lic. - Leave it next to the installer before running it and it installs itself. You can also copy it by hand afterwards, next to
golem-client.exe, in%LOCALAPPDATA%\Golem\. - Restart Claude.
Uninstalling does not delete the license. Reinstalling must not cost you asking for it again.
Without a license: evaluation mode
Without golem.lic, Golem works: it starts in evaluation mode, with the tools that look and one live connection at a time. The tools that act on the remote machine (run_powershell, stopping or starting services, starting or killing processes, writing files…) need a license: if you call one it tells you so (tope_de_evaluacion) and where to buy; it is not a fault. Same if you try to connect to a second host. The full list and the modes, one by one, are in Licensing.
