Installation steps

System requirements

Software

Presenter Mode on Windows

Preseria in Presenter Mode (where it integrates tightly with Office and automates launching and switching between PowerPoints, PDFs and videos) will work with all recent versions of Office, including Office 2019, but we recommend using the latest and continually updated Office 365 (also known as Microsoft 365).

The Preseria desktop app itself does not have specific minimal or recommended hardware requirements and is low on resource consumption, but for a smooth experience and efficient presentation file switches and as a general rule of thumb we recommend using presentation computers with modern and fast hardware (CPU & RAM) and enough memory to handle the presentation files in the gigabytes range.

  • CPU: 11th Gen Intel Core i5, i7 or newer processor.
  • Memory: 16 GB DDR4 2133 Mhz or faster RAM.
  • Network: Gigabit or faster Ethernet (wired) for reliable and high speed file transfers.

Info

Our Recommended Hardware list is purely based on experience from using Preseria on various Windows laptops and roughly measuring the time it takes to open, close and switch between typical presentation media (PowerPoints, PDFs, Videos) in FullHD (1920x1080). Your actual system requirements fully depends on what kind of presentation media you expect to display. Decoding 4K video is more processor and resource intensive than showing still image slides etc.

Program Data Location

Windows: Preseria Windows program data is stored with your home profile in C:\Users\{user}\AppData\Roaming\com.preseria.preseriaAir

macOS: Preseria macOS program data is stored in two locations:

  • /Users/{user}/Library/Application Support/com.preseria.preseriaAir
  • /Users/{user}/Library/Application Support/Adobe/AIR/ELS/com.preseria.preseriaAir

Upgrading Preseria on macOS

If you’ve previously installed Preseria for macOS you might have to delete the program data directories for the new version to function. In case you get an error telling you that the Encrypted Local Storage can’t be opened after launching Preseria, then delete the folders above and restart Preseria.

Presentation Files Location

Windows: Downloaded conferences (and their presentations) are by default stored in your documents folder under "Preseria": C:\Users\{user}\Documents\Preseria

macOS: Downloaded conferences (and their presentations) are stored in your documents folder under /Users/{user}/Documents/Preseria

Notes

Keynote (.key) files on Windows

There's no viewer for Apple Keynote files available on the Windows Operating System, and likely never will be. You should let the presenters know (in the Email Invitation they receive from you) which file formats you'll accept.

Differences between the Windows and macOS version

The macOS version of the Preseria client currently only supports the simplified "Technician Mode", which means you'll be able to download and synchronize presentation files, as well as view the Sessions and see which files belongs to which presenters, but you'll not get the "seamless transition" offered by the "Presenter Mode" available on the Windows platform.
