Please update all computers that run Salon Iris.
Yes, all of the computers on a multi-computer or multi-location network need to be updated to the same build of Salon Iris. A good rule of thumb is to update the server computer with the salon software download first then update the remaining client computers.
Before updating we recommend making a backup of your database. This can be done by going to “File” and selecting “Backup and Restore”. Backing Up your database helps insure the safety of your information.
