Already using Dexterity Sheets?

Nothing to download. Within about 30 minutes the status bar shows Update to 1.2.0: click it and the app updates itself and reopens.

New install

File Who it's for
DexteritySheets-Setup.exe Everyone: download, double-click, done. No administrator rights needed.
dexterity-sheets-1.2.0-windows-x64.msi IT: the same installer for deployment tools (msiexec /i … /qn).
dexterity-sheets-1.2.0-windows-x64-portable.zip Run without installing (USB stick, test PC).
DexSheetsServer-Setup.exe The office server, for IT, once per office: installs the server as a Windows service and the Server Manager (people, bulk import, updates, backups) (guide).
DexSheetsServer-1.2.0-x64.msi The same server installer for deployment tools.
SHA256SUMS Checksums of every file above.

Windows may say "Windows protected your PC" because the installer is not code-signed yet: click More info → Run anyway.

What's new in Dexterity Sheets

  • The office server installs from DexSheetsServer-Setup.exe (or the .msi): a Windows service that starts with Windows and restarts itself, the firewall opened for the office network only, the data folder locked to administrators.
  • New Server Manager for IT: start and stop the server, see how teammates reach it, add people one by one or many at once (type them, paste from Excel, or import a filled-in template), reset passwords, change roles, disable or remove people, manage app updates, back up and restore. No commands to type.
  • The office server never offers its own installer to office PCs as an app update.
  • Deleting a shared workbook on the server now works on Windows even after someone has opened it.
  • Fixed: if the server PC lost power in the middle of saving an edit, the next edit could be lost at the following restart. It is now kept.
  • A damaged snapshot on the server is now recognised and the previous good one is used, instead of showing a near-empty workbook.
  • The server stays light over months of use: workbooks nobody has open leave memory, its edit log and its own log file no longer grow without end, and hourly automatic versions thin out with age (all from the last two weeks, one a day for three months, one a week after that). Versions someone kept by name are never removed.

All changes: v1.1.0…v1.2.0
