I've created some useful utilities and put them in a lovely menu for my colleagues so they are there each time they open Excel. Once the testing has been completed it is going to be released company wide and it could potentionally be used by 150 + users at once.

Is there a maximum number of times a single Add-In can be accessed. I plan to have just one live file on the system that people will use so it will be easier to update.

Also does anyone have a good way of "kicking" people out of the addin so that I can update it and do not have to organise 150 people to exit excel.

Many Thanks
