Installing & the “unknown publisher” prompt

Run TellsheetSetup-Windows.exe. If Windows shows a blue “Windows protected your PC” screen, click More info → Run anyway — the installer is published by Souq E Kamil Trading and Solutions WLL. Open Excel afterwards and the Tellsheet tab is already there. Remove it any time from Add or remove programs.

For teams & admins

Roll it out to everyone

Microsoft 365 admins can deploy Tellsheet to a whole organization from the Microsoft 365 admin center → Integrated apps, sourced from AppSource — no per-user setup.
