Installation Path Dialog

This dialog allows you to select a validation method for the selected installation path. The actual validation is performed when pressing [Next ] button.

Use native Windows Installer validation

The default option. The installation path is verified automatically by Windows Installer using its standard mechanism. This validation is usually restricted to checking if the path can be accessed of if the specified drive exists.

Display an error if the installation folder already exists

Displays a standard message box with an error if the selected folder already exists on disk. The installation folder dialog will remain visibile.

Ask about overwriting the installation folder if it already exists

If the selected folder already exists on disk, a message box will ask the user about overwriting it. If the answer is Yes, the installation continues. Otherwise, the installation folder dialog will remain visible.

Display an error if a specific file or subfolder exists in the installation path

This option allows you to specify a relative path which can point to a file or subfolder. If the final resolved path exists on disk, an error message will be displayed and the dialog will remain visible.

If you want to check if a file exists, you can use the actual filename:

filename.ext

Copy

If you want to check if a folder exists, you can use the actual folder name:

Folder Name

Copy

You can also use paths relative to the installation folder:

Subfolder Name\Another subfolder\filename.ext

Copy

Subfolder Name\Another subfolder

Copy

Display an error if a specific file or subfolder does not exist in the installation path

This option allows you to specify a relative path which can point to a file or subfolder. If the final resolved path does not exist on disk, an error message will be displayed and the dialog will remain visible.

It supports the same format as the above option.
