Hi,
I came across this during a Citrix (Application Streaming) class and not following one of the Basic Rules we started to virtualize an application that we never had seen before: Google Chrome. Well, "profiling" failed with a Chrome installation error so I gave it a try on an App-V 4.5 RC sequencer.
Luckywise Chrome installation suceeded, I was able to run the App during Monitoring but then - the whole package was about 512 KB in size, nothing usefull in the VFS.
It turned out that Google Chrome installes into "Local Settings / Application Data", a location, that App-V "excludes" during Sequencing.
Removing LocalAppData from the exclusion list led me to the same error I've seen on the Citrix Profiler (well, I did not compare the error codes..), so that did not make the trick.
What does work is if you copy "Local Settings / Application Data / Google" to something like "Q:\8.3\Goolge" during Sequencing.
Do not forget to adjust the Shortcut(s) to this new location.
On the XP-Client, Google stores the User's setting into Local Settings / Application Data" as well (have not tested this on Vista).
Annoying things about that: Chrome does not provide an offline installer and Downlod takes quite long (15 minutes for 7 MB - (Wo)Men, it that Google...? :-\ )
Secondly - it does not use Windows Installer nor does it install to protected areas so I'm afraid within a week or two we will have a Google Chrome installation in every User's Profile on every Terminal Server and Fat Client. Maybe Google tries to establish a Bot-Net on Windows PCs (bad guess, I know ;-) )
SERIOUSLY: Please do not try to launch a discussion about Google's behaviour nor its realtionship to MSFT here - this would be Off Topic !
