What type of software is QStudio?

  • It can run on every OS platform including windows, mac, linux.
  • 99% of the source code is available at QStudio github
  • It operates totally within a users profile and has no administrative priveleges.

How is it easiest to deploy QStudio Firm wide?

QStudio runs on all operating systems and has separate packages for each. It really depends on your firm and what computing systems your target employees have.

Most firms have used the windows installer to deploy QStudio firm-wide.

What installer does it use?

QStudio packages an installer using Inno Setup, this allows for a number of options for automated setup including: /SILENT, /VERYSILENT /ALLUSERS . More information is available at: Inno Setup Command line

Are packages versioned

yes, all installer and jar packages contain version information and are digitally signed using SHA384RSA to prevent tampering. QStudio uses semantic versioning and all changes are listed in the release notes.

What Enterprise Roll-out policy would you recommend?

  • All QStudio releases are thoroughly tested , this is balanced against the need to release new features quickly.
  • For stability we do not recommend enterprise users to update all users to every release as soon as it occurs. You should instead wait for a period after release and use a longer-term supported release that has been time-proven.
  • If possible we recommend allowing users to choose when to upgrade.
  • Firm-wide compulsory updates should only be used for time-critical updates.
  • QStudio release notes will provide guidance. Additionally QStudio itself can check for updates and provide notifications.

What issues have you seen affect Enterprise wide installs in the past?

One packaging department within a firm insisted on running the uninstaller of the older version before running the new installer, this caused all user settings to be removed resulting in 10-20 users contacting Timestored saying all their settings had been wiped. There was nothing we could do. The best practice of all installers is to remove everything if uninstall is requested. We would recommend backing up your server connections.
