How To Resolve “Error Code: 100006000” in Zoom

Dealing with error code 100006000 in Zoom can be super frustrating, especially since it pops up right around 90% of the way through the install. Basically, Zoom hits a snag because it can’t copy over critical files like ssb_sdk.dll. Usually, it’s a permissions thing—your system might block these files from being written or the installer doesn’t have enough access. Sometimes, other culprits include interference from antivirus, firewalls, or even tiny things like low disk space. A lot of folks stumble here because Windows isn’t playing nice or because the installer gets blocked midway, so knowing some fixes can really help get Zoom installed without crying over it.

How to Fix Error Code 100006000 in Zoom

Check if your drive has enough free space

This one’s kind of obvious but often overlooked. If your C: drive or whatever drive you’re installing on is full or nearly full, Zoom might fail to write necessary files. Windows sometimes just won’t bother telling you why, it just stalls, and you see that error. Make sure you have at least 2GB free, especially if your drive’s a bit cramped.

• Open File Explorer.
• Click on This PC and look at how much space’s left on your main drive (usually C:).
• If it’s less than 2GB, time to clear some junk — delete temp files, old downloads, or uninstall apps you don’t need anymore.

Quick space cleanup:

1. Press Windows + R, then type cleanmgr and hit Enter.
2. Select your main drive (probably C:) and click OK.
3. Hit Clean up system files.(You might need admin rights for that.)
4. Pick the files you no longer need (like old Windows updates, temp files) and delete them.

If this still doesn’t free up enough space, check out a detailed guide on how to clean unnecessary files from your Windows. Sometimes a good cleanup does the trick before you even run the installer again.

Temporarily disable Windows Defender or antivirus software

Because of course, Windows and other antivirus tools have to make installing programs more complicated than it should be. They can mistakenly flag parts of the installer or files it needs as threats, which can cause the copy process to fail. Disabling real-time protection or your antivirus temporarily might be just enough for Zoom to install smoothly.

For Windows Defender:

• Open Settings (Windows + I).
• Select Privacy & Security.(On some versions, it might be just Update & Security.)
• Click on Windows Security, then go to Virus & Threat Protection.
• Under Virus & Threat Protection Settings, click Manage Settings.
• Turn off Real-time Protection. A quick note: on some machines, this might require admin rights, or it might turn back on automatically after a while. Not sure why it works that way, but it’s worth trying.

For third-party antivirus apps (like Norton, Avast, McAfee):

• Find the antivirus icon in your system tray (bottom right).Right-click it.
• Look for options like Disable Protection or Turn Off. Pick a temporary duration — 10 minutes, an hour, or until you restart.
• After disabling, try running the Zoom installer again.

Remember to turn your antivirus back on after installing, because safety first, y’know.

Extract the installer before running it

Running the installer directly from a ZIP or compressed folder can cause problems—Windows might not give the installer all the files it needs, or the extraction process might interfere. It’s a good idea to manually unzip the download and run everything from the uncompressed folder.

• Navigate to where the Zoom installer was downloaded (probably Downloads folder).
• Right-click the ZIP file, choose Extract All…. Pick a convenient location (like your desktop).
• Open the extracted folder, find the ZoomInstaller or similar setup file.
• Right-click and select Run as Administrator — this can help with permission issues.

And then just follow the prompts. Sometimes, running as admin in Windows can be a game-changer for fixing access stuff that causes errors like 100006000.

Honestly, a lot of times this error boils down to permissions or interference. Clearing space, disabling antivirus temporarily, and running the installer from an extracted folder cover the most likely culprits. On some setups, these fixes are enough to push through and get Zoom installed smoothly.
