Problem: 1) all users to have excel 2003 as the default application (installed locally)
2) a specific group of users to have access to an APP-v’ed version of Excel 2010 (published to them via citrix PN Agent)
3) when the 2010 users double click a .xls file or a .xlsx then we wanted App-V Excel 2010 to be the default application.
Our simple (though not necessarilty the best approach) was to have a logon script run for the Excel 2010 users which ran the following commands
ftype Excel2010=sfttray.exe /launch “Excel2010” %1 %*
we also needed to ensure that NO file associations for 2010 were assigned in the APP-V package (otherwse 2010 was taking over for all users of the server it was installed on)
we also needed to check that there were no user specific reg keys for file associations in the users HKCUSOFTWAREclassses
