Two years ago I created a labview application and have several hundred users.
Now I would like to distribute version 2 of the application. I would like to have the installation procedure do the following (with as little user effort as possible):
1. search to see if version 1 is installed. If not, simply install version 2 as a new install.
2. if version 1 is installed, copy all data files created with version 1 to a safe place.
3. install version 2.
4. take the saved data files and move them to directories to be used by version 2.
5. uninstall version 1.
I am looking for some guidance from people who have been through this. I can think of a number of approaches:
1. write a labview vi which does all of the above. I think it is possible but it may be a lot of work.
2. figure out a way to make the labview installer generator do the above. Don't know if this is possible.
3. Use a windows scripting language like VB script or Perl. Unfortunately, there is a significant learning curve here.
4. Some combination of the above or a completely different approach.
Any help will be sincerely appreciated.
David
