Just evaluating Advanced Installer. We are testing a small upgrade to an existing application (already installed on target PCs). I want to install a single file "a.dll" into a target directory where an older "a.dll" already exists. When we run the Advanced Installer MSI file, the install appears to complete OK, but the old file is still there and the new file hasn't replaced it, but it gives the impression that everything worked (no errors + upgrade appears in add/remove programs!). We then Remove the new MSI installation and the old file is deleted!
How do I overwrite existing files?
Thanks
