INTRODUCTION
If you install a Microsoft Windows Installer package by using a version of Windows Installer that was released earlier than version 2.0, the length of the data value of the  key is 31 characters.

However, if you install a Windows Installer package by using Windows Installer version 2.0 or later, the length of the data value of the RunOnce key is 30 characters.



MORE INFORMATION
By default, the length of the data value of the RunOnce key is 30 characters in Windows Installer 2.0 or later. However, sometimes the length of the data value of the RunOnce key must be 31 characters. In such cases, you must prepend a special character to the data value of the RunOnce key to make the RunOnce key 31 characters long.
