MSI Installer Limitations

I have spent the last few days creating a few MSI packages and fixing some pre-existing MSI packages. One issue that I found with working on an MSI that installs files to a Hidden partition is that InstallShield has very little in the way of control over partitions, mountpoints and the like. This was not really an issue, as I am using a SOE and can Mount Volumes through VBScript.

The one issue that we had with mounting this specific Volume is that if a USB Drive or a Virtual CD/DVD drive is installed on the machine, it modifies the volume numbering scheme. The volume we were previously attempting to mount was Volume 3. This became Volume 4 in the even that another drive was connected, or a higher number depending on how the USB drive was partitioned.

Not a grand issue, but one that was overlooked by the Corporate boys when they released one of their imaging tools (the hidden volume is the Image volume). I modified their install script to use a bit more smarts when attempting to find the volume it needs. (continue reading…)
