I've changed the batch file, and confirmed that if a workstation visits the URL of one of the MSI files that it can download it okay, however when I run the Live Installer batch file on the same client I get the command window pop up for a few seconds and then I get the error:
"This installation package could not be opened. verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package."
Again, if I copy and paste the URL of the MSI file out of the script and run it, the installer runs without an issue.
Any ideas?
Edit: I am using a https link to the file, could this be the issue?
Edit 2: I've tried it other ways now too, but through the batch file I always get the same error.
Edit 3: I've generated a fresh Live Installer to make sure I've not got anything wrong, but I am still getting the same thing... What on earth is happening here?
