Most of the major commercial packaging toolsets have wizards to guide you through setting up a system search for a folder.

For example, in AdminStudio's InstallShield Editor tool you would click on System Search then Add.. then in the drop down list click one of

(i) "Folder Path, by seaching all drives"
(ii) "Folder Path, by searching in a specific folder"

depending on where you wish to search. If you take option (ii), then specify the folder name you wish to search for, supply the full path to the parent folder and then set the number of subfolder levels to search to 0. On the next screen you can enter your own property name and take the option to use this property in an Install Condition

If you don't have access to this wizard-driven approach, then to do this from "first principles" would involve the following :

(this example assumes you are looking for a folder named C:\Program Files\Acme)

1) using ORCA or similar table editor, add a row to the DrLocator Table with the following values

Signature : AppDir
Parent : <Leave Blank>
Path : C:\Progra~1\Acme
Depth : 0

2) using ORCA or similar table editor, add a row to the AppSearch Table with the following values :

Property : MYDIR
Signature : AppDir

3) using ORCA or similar table editor, add a row to the LaunchCondition Table with the following values :

Condition : MYDIR <> ""
Description : The product cannot be installed because the ACME folder was not found on the system

- obviously you should alter the above Description field to meet your own particular needs (e.g. localized text)

Note that because the system search is for a folder and not a file, you do not need to add anything to the Signature table.

Hope this helps,

VBscab help me further to implement launch condition. Spartacus already showed you how. Use this post, together with your authoring tool's help and/or MSI.CHM, the Windows Installer help file which will almost without question have been installed with the tool you're using.
