Using ZCM 10.2

I have created Windows MSI Bundles to install programs to Windows XP

The MSI's only seem to install properly when I choose the option to
upload the MSI and associated files to the Zenworks Repository.

They don't install properly if I create the bundle and choose the option
to use the UNC path to a network location of the MSI.

I noticed that the MSI Properties section auto populates with the
property values when I upload the MSI to the repository, but it remains
blank if I choose the UNC path option.

I assume there must be some type of bug with the UNC option ?

Has anyone else noticed this ?
