i need to delete folder that is created at install time and has files that are created while application is run. i am using the Basic MSI project. i tried making a custom action which deletes folder while uninstalling application. i am using
DeleteDir(directory-name , ALLCONTENTS) but it is unable to delete the files created while running the application.
DeleteDir can't delete files/folders that are in-use.
You need to determine which files are in use and why and update your setup to close these files before the delete occurs. This may require calling UnUseDLL, FreeLibrary, etc. to release the appropriate file.
