I'm sorry for my delay reply.
Yes, you can store the related information provided by the user during first time install. For this, you can create a XML File
in the Files and Folders
So, a .xml file will be creating during installation time. During an upgrade, you can retrieve the information from the related .XML file. Please take a look on the XML Locator Search
article withe related information for hints and guidance.
By the way, I've attached a sample project which implements this scenario, so if you are interested to take a look directly at my project, you are more than welcome to download the ZIP file.
As you will notice, during installation the user is asked to enter some information. Please fill the related fields.
After you build and installed the sample app, you can go in the Product Details
page and increase the Product version
(when prompted, please select the major upgrade
option). Rebuild the package and launch to install it. Notice that the fields already contains the previous entered values.
Let me know if that helped.
