Can not install Windows 11 Insider Preview Feature Update (26340.9233) I have tried multiple times (8-9) on different days, to download and install Windows 11 Insider Preview Feature Update (26340.9233) but each time it says "ERROR try again later!" Is there a fix?

Hi BEN HADDOX,

Since the update is failing repeatedly with only a generic "Try again later" message and no specific error code, it may help to check whether the issue is related to the Windows Update components rather than the Insider build itself.

You can try the following:

Open Command Prompt as Administrator.
Run: sfc /scannow
After it completes, run: DISM /Online /Cleanup-Image /RestoreHealth
Restart the PC and try the Insider update again.

If the update continues to fail, please share any update error code shown in Settings > Windows Update > Update history or in the Windows Update failure notification. The specific code can help narrow down whether the issue is related to servicing components, storage, drivers, or Insider channel enrollment.

I hope this helps point you in the right direction. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.

Try these steps in order:

Disconnect all non-essential external devices. Remove items such as USB drives, external hard drives, printers, scanners, speakers, and docking stations. Peripheral devices can interfere with upgrade installation.
Make sure Windows is fully updated first. Open Start > Settings > Windows Update and install any available updates for the current build, then restart the PC and try the Insider update again.
Temporarily remove non-Microsoft antivirus and other nonessential software. Go to Control Panel\Programs\Programs and Features, uninstall third-party antivirus or older nonessential apps, restart, and retry the update. These can block or interrupt upgrades.
If the update is failing near the end of installation, run component cleanup. Open Command Prompt as administrator and run:
```
   dism /online /cleanup-image /startcomponentcleanup
```
Then restart the device and check for updates again.
If background software may be interfering, perform a clean boot and retry. This is specifically recommended for update failures caused by another process running in the background.
If the Insider update still repeatedly fails after multiple attempts, submit the issue through Feedback Hub under Install and Update > Downloading, installing, and configuring Windows Update so diagnostic data can be collected for the Windows Insider team.

If the device is in an Insider channel and Windows Update continues to fail, another supported path is to download the latest ISO for that Insider channel, mount it, and run Setup.exe. Back up files before doing an in-place upgrade.
