UiPath Platform Installer fails after download phase

Help Studio
1

Hello,
I am unable to install UiPath Platform (Community Edition). The installer always fails right after the “Downloading” phase finishes.
The installer UI the second installation phase never starts.

What I already tried:
Removed hidden MSI product using Microsoft Program Install and Uninstall Troubleshooter
Cleaned %TEMP% and C:\Windows\Temp
Deleted C:\ProgramData\UiPathConnected and C:\ProgramData\UiPath
Reset Windows Installer (msiexec /unregister + msiexec /regserver)
Ran DISM /Online /Cleanup-Image /RestoreHealth and sfc /scannow
Tried /qb and /qn MSI installation modes
Tried running installer as Administrator
Tried default installation path
Verified permissions on AppData and ProgramData
Of course, after each attempt I carefully cleaned the system.

Symptoms:
Download phase works normally
After download reaches 100%, installation fails immediately

I installed UiPath on my desktop PC without any problems. The installation still fails on my laptop. Both systems are running Win 10.
I have created UiPathPlatformDiag-232bbaaf.zip, unfortunately I can’t upload it here. That’s why I uploaded it here.: [link removed, but we got the file //forum moderator team]

Thank you for this report @Vokin

I created an issue for this in our internal tracker and forward it to our Studio team. I also grabbed the file you shared and remove the link from your post.

Hi @Vokin

I’ve seen this behavior before when the bootstrapper finishes downloading but fails to hand off to MSI.

A few things that helped in similar cases on Win10 laptops:

  • Temporarily disable antivirus / endpoint protection (Defender included) and try again.
  • Make sure TLS 1.2 is enabled in Internet Options → Advanced.
  • Check Event Viewer → Application logs right at the failure time (usually MSI or .NET errors show up there).
  • Try installing only UiPath Studio (standalone installer) instead of the full Platform to see if it proceeds.
  • If the laptop is on a corporate network, try a different network (no proxy/VPN).

Since the same installer works on your desktop, it’s very likely something environment-specific on the laptop rather than the installer itself.

Hope this helps.

Thank you for the answers - turning off Defender (or antivirus) is self-evident when the installation fails, and the fact that the installation on the PC was possible only to the default location is not even mentioned as a problem, even though it bothers me. So far I have solved the problem by offline installation of the older version of UiPath 23.4.2, although there are problems with updating to the latest version. It’s a shame that there are already basic problems with UiPath during the first steps.
