The most simple solution for storing the information whether to show the message again or not is in the project's Properties. Therefore, and since you didn't tell us how exactly you did it, I will assume that you used that facility.

Properties get saved on the target machine in an xml file somewhere in "Documents and Settings\#YourUserName\Application Data\#YourApplicationName\#Version\user.cfg" or something similar, depending on what version of Windows the target is running.

Check if that config file is deleted during de-installation. If not, then it will cause the application (of identical version) will still know that is shouldn't show the message again.
