The type of start condition can be specified in the Microsoft .NET deployment environment including:
File start condition This condition determines whether there is a file on the target computer. If the conditional setting is false, the installation is terminated. Registry Start Condition This condition determines if there is a registry key on the target computer. If the conditional setting is false, the installation is terminated. Windows Installer Startup Condition This condition determines whether there is a Microsoft Windows installer component on the target computer. If the conditional setting is false, the installation is terminated. .NET Framework start condition This condition determines if a .NET runtime library file is installed on the target computer. If the conditional setting is false, the installation is terminated. Internet Information Service Startup Condition This condition determines whether Microsoft Internet Information Services is installed on the target computer.

Use the start condition editor that appears to specify the conditions required to install on the target computer. In the Start-up condition window, select the "Requirements On A Target" node. In the "Operation" menu, click Add File Launch Condition. This creates a new search ("AppSearch") under the Search Target Computer node and creates a new start condition under the "Startup Condition" node. In order to set the start condition to check if there is a file on the target computer, you must first modify the search attribute to reflect the file you want to search. The search attribute is located under the search target computer node. For additional information about using a search, click the article number below to view the article in the Microsoft Knowledge Base: 307369 How to: Use Appsearch IN .NET Deployment Select a start condition under the Startup Condition node. If you want to modify the message displayed when the start condition is calculated as False, modify it in the Start Condition Properties window. You should also modify the Launch Condition Condition property, which makes the message when the condition is calculated as false. For this example, set this property to File Search. Note: You can modify the start condition condition properties so that it matches the type of start condition to use.
