When trying to detect Acrobat 6 BrowserHawk is returning that Acrobat is not installed when I know it is.
Acrobat version 6.0 was not available at the time BrowserHawk 6.x was developed. Therefore it does not know how to detect this version.
As a result, when using BrowserHawk versions prior to 7.0, Acrobat will be detected either as Not Installed or as Version 5.
To resolve your issue, please upgrade to the latest version of BrowserHawk.
