This error Invalid Procedure call or argument error might be seen in the desktop version of Nutritionist Pro™.  It might be seen during the data update process and the reason for the error is some data issue.  It could be related to some data that the user has typed which is breaking the update process.    


Our first recommendation is to make sure if you are not using the English language during update process to switch your machine to the English language just during this process, you can change back to your native language after the update.  

If this is not your reason then there is a chance you have some data that is breaking the db update.  Contact our team and we can discuss options based on your case.
