Independently of whether it is the very first time you run your app, a good way would be to check everytime your app starts, whther the file containing the app version and other info, exists. For this, simply use 'file.exists'. If it is found, load data, if not, create it (or recreate it in case of an accidental deletion by user for e.g.) and then proceed to neccessary checks.

I would personally use a file to store the information. There are a few good link on the topic on this forum.

E.g. I personally use a file for storing external DB connection strings for monitoring MySQL DBs. Use 'If File.Exists(file location) Then blah blah blah', if there is no file then create one and store your data in it.
