New Post: Deploying Firefox

Hi rmdtech,

for the original Firefox setup.exe (not the FrontMotion .msi), a simple is-installed-rule would be to check the FileVersion of firefox.exe. But keep in mind to compare to the file version that you find on the details tab of the file's properties - this might be different from the product version! For the current esr installer the rule would look like:

<bar:FileVersion Path="MozillaFirefox\firefox.exe" Comparison="EqualTo" Version="45.0.2.5945" Csidl="38"/>

An similarily simple is-installable-rule would be to check if the file doesn't exist at all or the file version is less than the one you're installing:

<lar:Or>
<lar:Not>
<bar:FileExists Path="Mozilla Firefox\firefox.exe" Csidl="38"/>
</lar:Not>
<bar:FileVersion Path="Mozilla Firefox\firefox.exe" Comparison="LessThan" Version="45.0.2.5945" Csidl="38"/></lar:Or>
