If you have the latest version of the Showcase Workshop app for Windows (known affectionately around the office as 'Showcase XE'), your PDF files will display natively within the app.
You can always allow files to open in a third-party app if you prefer.
If you've got the current version of the app, you'll be able to launch it with our fetching blue flower icon.
Note: Some users might have an outdated legacy version of Showcase Workshop. If your icon doesn't look like the one above, download the latest version or flick us an email with any questions!
