In my experience, installation dates are not recorded in any kind of predictable way by the various product publishers, and it is not something that BFI is able to scan.
In a long running BFI implementation, the
First Used and
Discovery Start date columns in the various reports would be analogous to Installation date.
In a new implementation, these dates will reflect when BFI was deployed, more so than when a new application is discovered for the first time after installation. Note that
First Used reflects application usage information and may actually precede the
Discovery Start date.
