Error message when upgrade

delete file failed code 5 when trying to upgrade program

Can you provide a screen shot? In what part of the installation did the error occur? Which operating system? 32 or 64 bit? Was the application running while running the installation?

If the application is running, that won’t work. Once in a while the thumbnail preview tool (LBThumbnail) is locked by the OS and prevents updating it too. In this case, you can uninstall the old one, then install the new one, and that will work.
