I keep updating an Add-in for my users every few weeks. each time I call it
with it's new version name (started with Power1.0.xla , but now already
Power5.3.xla)

Is there a way I can put a code on my users workbook - let say on Sub
Workbook_Open() to check that the user has the last add-in version - and if
he/she does not to install the last version for him/her (the add-ins are
saved on a shared drive - so they all have access to it).

Many thanks

Dan
