Overview

Silent install steps

Sigil installs through a PowerShell command, so run it in an elevated PowerShell session. Command Prompt cannot run this cmdlet.

Install with PowerShell

1. Download or stage the installer (Sigil-Ebook.Sigil.2.8.0.X64.exe) to a local folder, for example C:\Installers.

2. Open PowerShell as Administrator — right-click Start (or press Win+X), then:
   • On Windows 10: choose Windows PowerShell (Admin).
   • On Windows 11: choose Terminal (Admin) — it opens Windows Terminal running PowerShell.

3. Run the silent install command:

Sigil-Ebook.Sigil.2.8.0.X64.exe /SP- /SUPPRESSMSGBOXES /VERYSILENT /NORESTART /ALLUSERS /COMPONENTS="dicon,*afiles

Deployment Notes

Key facts to confirm before rolling this out to production machines — permissions required, scope of install, and reboot behavior.

Detection Rules

Configure your deployment tool with the detection rule below to confirm a successful install of Sigil. The same rule work for Microsoft Intune, SCCM, PDQ Deploy, and most RMM platforms — just paste the values into the matching fields.

Registry detection

PowerShell detection script

Prefer a script-based check? Use this as a custom detection script in Microsoft Intune (or any tool that supports detection scripts). It exits 0 when Sigil is detected and 1 otherwise.

$Key = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\Sigil_is1'
$Value = (Get-ItemProperty -Path $Key -Name 'DisplayVersion' -ErrorAction SilentlyContinue).'DisplayVersion'
if ($Value -eq '2.8.0') { exit 0 }
exit 1
