Hi @ziyi020,

Check if you have Missing/broken WebView2 Runtime.

If still stuck:

  • Close UiPath Assistant fully (Task Manager → end UiPath.Assistant processes)
  • Delete %LOCALAPPDATA%\UiPath\Assistant
  • Reopen Assistant

If browser still says “re-download” the Assistant isn’t running, or the uipath-assistant:// protocol isn’t registered → uninstall and reinstall freshly again which should resolve the error.

Cheers!

Hello, I have downloaded the WebView2 Runtime as you mentioned, but after it shows 100% installed, the software does not appear on my computer and I cannot find it.

hiii @ziyi020 ,

Hi, you can try a few things:

  1. Restart the PC and try opening UiPath Assistant again.

  2. Check if the UiPath Robot/Assistant service is running in Windows Services.

  3. Make sure your Windows user has permission to run UiPath Assistant.

  4. Try repairing or reinstalling UiPath Assistant.

  5. If it keeps showing “re-downloading,” check your internet connection, proxy, or firewall settings.

  6. Also make sure you have the latest supported UiPath Assistant version installed.

If it still doesn’t open, checking the UiPath Assistant logs may help identify the exact issue.

After multiple attempts to redownload, all my downloads have failed. Now it looks like this:

Hi @ziyi020, thanks for sharing the screenshot. I can see that the download is completing successfully, but the installation itself is failing.

Please try these steps:

  1. Close the UiPath installer completely.
  2. Restart Windows.
  3. Run the UiPath installer as Administrator.
  4. Make sure there is enough free space on the C: drive.
  5. Temporarily check whether antivirus/firewall is blocking the installation.
  6. If it still fails, please check the UiPath installation logs. They should give the exact reason for the installation failure.

Since the download is completing, this looks more like an installation/permission issue rather than a download issue.

Hi @ziyi020

honestly I think this thread is getting a lot of generic checklist answers that wont get you anywhere, restart, run as admin, check antivirus, none of that is based on what actually failed on your machine

from your screenshot the download finishes fine and only the install step errors out, so the real reason is in the installer log. Theres a button at the bottom left of that failed screen that looks like its for collecting logs, if you click it and paste the file here, someone can tell you the actual error instead of guessing

one thing worth checking meanwhile, since you retried several times, a broken partial install may be blocking the next attempt. Look for a UiPath folder under %localappdata% and in Program Files, and check Apps and Features for any UiPath entry to uninstall properly first
