Once you receive your license link from MainSpring (this link will look like this: https://accounts.filemaker.com/software/license/LICENSEKEY), you are ready to install FileMaker Pro on all of your computers.
We recommend utilizing the Windows 64 bit installer for the best compatibility with FormPro. There is only one installer for Mac OSX.
On the link above, the first step is to download the license certificate. This is read from the downloads folder by the FileMaker installer in order to license your FileMaker software. Click the blue "Download" link under license certificate, and save the .fmcert file to your downloads folder.
Scroll down the page, under the "FileMaker Pro Advanced" section, download your corresponding installer. You can ignore the "FileMaker Server" section, as MainSpring will setup your server as part of the installation process for FormPro.
After downloading the installer, you can run the installer, following the prompts that it gives you along the way. Once installed, your users will be able to connect to your FormPro server.
