Here is a usefull link for all those who make deployment (setup) projects using visual studio.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/property_reference.aspΒ
It is a list of properties that can be used for Launch conditions.
Based on the above info i will give you an example.Β If you want to create an installer that only the administrator will execute, you can create a launch condition and in it’s property ‘Condition’ place ”AdminUser” (without the quotes). If you read the above link you will know that AdminUser is true if the current user executing the installer is an administrator. If this condition fails then a dialog box appears containing the error message that you provided in the property Message.
Cheers
