ExcelMaster v0.6.25

May 3, 2026

Fixes fresh-install Office add-in activation by invoking the verified VSTO customization installer during setup.

ExcelMaster v0.6.25

What changed

  • Fresh installs and repair installs now actively launch the Microsoft Office customization installer to register the ExcelMaster add-in.
  • If Office requires confirmation, the verified publisher prompt appears during setup, and the add-in loads after the user chooses Install.
  • If Office add-in registration cannot be completed, setup now fails with a clear error instead of finishing while ExcelMaster is missing in Excel.

Notes

This release improves the installation flow for fresh installs, reinstalls, and repairs. Users whose ExcelMaster add-in already appears in Excel do not need to take extra action.
