Hello all,

I am a long time user of insync. I noticed this issue only this last week where my insync app on Windows will not start. When manually starting the application, I am greeted with an error message titled: Fatal Error Detected. Error description is “Failed to execute script main”.

My system details

  • Windows 11 24H2 build 26100.3624
  • Insync App 3.8.7.50505 (newest downloadable from insynchq site as of today)

I have not made any changes to my insync settings in recent months. I am unsure what has changed to cause this app to stop working. I have uninstalled insync from my system, rebooted, then installed anew using the install file from insynchq.com. Even a fresh insync app install still fails to launch.

Any ideas on what I can do to resolve this issue?

Hi @Nathan_Hancock ,

My apologies for the issue! Could you clarify if you did a full uninstallation before reinstalling Insync? This includes removing the %AppData%\Insync folder as shown here.
