It has been difficult at sometimes, the support people at one point told me that they couldn't tell me information about OfficeScan because it was knowledge that was passed down from engineer to engineer. The issue was that if you used the msi for the install any further installs would require the msi to have the same exact name or else the install fails and corrupts the install. This information is not listed anywhere on trends website. Support kept trying to get me to use the exe for installs instead, but we use
SCCM and msi's work better. We had to write a script to come up with a solution so that we could uninstall the software and install the new software. Trend did provide the technical expertise to help with the script and had us work with one of the developers in order to resolve that issue. So they did fix their screw up but it took a while and several complaints.
