I've had a problem with most msi tasks in LDMS 9.6
They almost always report as installing successfully but that is false.
Nothing is installed, no log files are created, nothing shows up in event viewer and no files transferred from the core server to the workstations.
This is a issue with most msi packages that I've created, different applications, packages and tasks have been recreated but no luck.
If I create a batch file that executes the msi files, everything works fine but that is not something I would like to do to all my packages.
