For instance I did not require the licence dialog so I deleted it from my installation. When I built the install I observed that the AgreeToLicense radio buttons were still entered in the RadioButton table.
So i exported my project to an .ISV file and found the entries for the AgreeToLicense radio button group. I noted the code (R801) and deleted all the lines related to AgreeToLicence and R801. I then reimported the .ISV and there is now no trace of AgreeToLicence in my install.
Does anybody know if I am likely to come across some problems in the future as a result of this? The .ISV file contains plenty I do not understand but this seemed quite safe. (I looked at the changes after adding a radio button groupl to make sure I didn't miss anything).
