How do I check for a file and delete it, if found?


Use a Wisescript custom action to either search for a file or use Check if File/Dir exists, then delete file.  Use a Set Variable custom action for the path to the file that should be searched for and also in the Delete File action. 

Check if File/Dir exist then
Delete File
End Statement.

For Example:

Set Variable TEST to C:\TEST
If File or Directory exists %TEST%\File.txt
Delete File(s) %TEST%\File.txt
End Statement

The Check if File/Directory exists action gives you the ability to Display a message only, Start an While loop or Start Block as shown above or abort the installation.
