I would disagree with this answer, as I myself have many instances wherein I have installed the latest version & it still keeps on blinking the old one.
I have got FireFox 19.2 installed, however SI is still showing as 18.0.1 & also that it shows the latest version to be 19.0 & not 19.2.
Again I have bit torrent installed of version 22.214.171.124039, while SI is showing it as 7.8.
Again, there is software CDisplayEx, which has the latest version & the last ever version as 1.8, while SI & the website of SI is showing as 126.96.36.199, whereas there is no version like that. I even sent this for correction but it is still reflecting as 188.8.131.52.
I agree with Gary.
