Hello Michael and welcome to Advanced Installer forums,
In order to achieve that, you can proceed as it follows:
1. First, you can create a
search for the "D:\" drive. Based on this search, we will force the installation in
"D:\Program Files" folder.
2. After creating the search, you can go to
"Dialogs" page --> select
"FolderDlg" from
"First Time Install" section --> click on the
"Next" button --> under
"Published Events" tab click
"New..." and create an event as it follows:
Event: Set installer property value
Property: APPDIR
Argument: D:\Program Files
Condition: <the_property_which_stores_the_result_of_your_search>
This way, if the search was correctly done, we will modify the value of the
APPDIR property (this property represents the installation folder).
Hope this helps.
Best regards,
Catalin
