Attempting the installation of ArcGIS Desktop, Concurrent or Single Use, returns the following error message:
Error 1316: A network error occurred while attempting to read from the file <cd>:\ArcGIS\ArcGIS.msi
Installations for both Administrative Network use and Individual use cannot exist on the same machine if they are for different product types.
For example, attempting to install ArcView 8.1 Single Use on a machine which already has ArcInfo 8.1 installed for Individual Use.
Do not install a network installation of ArcGIS Desktop if an individual use installation of ArcView Single Use exists on the machine, or vice versa.
You can install the Administrative Network copy and Individual Use copy on the same machine so long as you are using the same product. For example, ArcView Single Use Individual and ArcView Single Use Administrative Network.
