Application won't launch after installation

Steps to reproduce

  1. Download Obsidian 0.12.15 installer and run it
  2. App completes installation with no error
  3. App attempts to launch, but does not appear on screen or in taskbar. 3 background processes appear in Task Manager however

Expected result

App to launch and be greeted by welcome screen.

Actual result

App fails to launch and instead opens up 3 background processes in Task Manager. Closing one of these instances will either reopen it, or a white box will appear but application will not initialize.


  • Operating system: Windows 10 Pro Version 21H1
  • Obsidian version: 0.12.15

Additional information

I am attempting to install Obsidian on my work laptop. I went through the approval process and their support have been able to install and run Obsidian without issue on a test computer. Additionally, it was pointed out to me that their test computer is running Windows 10 Version 20H2.

Other steps I’ve taken to try and troubleshoot:

  • Restarting and attempting to launch again
  • Uninstalling using the included uninstaller and reinstalling (same result)
  • Running the uninstaller, deleting the following directories and then installing again:
    • %userprofile%/AppData/Local/Obsidian
    • %userprofile%/AppData/Local/obsidian-updater
    • %appdata%/obsidian
  • Running installer as admin
  • Running app as admin
  • Running in compatibility mode for Windows 7 + 8

Screenshots below:

3 background processes that open when attempting to launch:

White box that sometimes appears when ending one of the background tasks:

Windows specifications:

The problem is not windows version. I don’t know. Maybe your computer has some windows policy in place that blocks obsidian.
Do you get any errors if you run it from console?
Do you see any errors in %userprofile%/AppData/Roaming/obsidian/obsidian.log

I don’t see any errors when running the .exe from the command prompt:

I also don’t see any errors in obsidian.log, it’s the same output as in the screenshot above.

“work laptop”

Its not an Obsidian issue. They forgot to give something permission to run.
