Install Mergi
Download
Download Mergi Setup from the Mergi page on xssit.com. The setup program is signed by XTREME SOFTWARE SOLUTIONS & IT, so Windows shows who made it.
Install
- Run the setup program you downloaded.
- Choose whether to install Mergi for you only (the default: no administrator rights needed, and updates install without a prompt) or for everybody on the computer.
- Read and accept the licence agreement. The setup shows it in English or Spanish, the language you picked.
- Choose the options:
- Create a desktop shortcut (not ticked).
- Add Mergi to "Open with" for PDF files (ticked). Mergi is added to the Open with menu of PDF files in Explorer. It never makes itself the default PDF app: you choose that in Windows.
- Click Install. At the end the setup prepares Mergi for a fast start, which takes a few seconds.
Upgrade
Run the setup of a newer version over the one you have: your settings, recent files and licence stay. Most of the time you will not need to, because Mergi updates itself from inside the app.
Uninstall
Open Settings › Apps › Installed apps in Windows, find Mergi and choose Uninstall. Your settings stay in %APPDATA%\Mergi; delete that folder too if you want to remove them.
