Good morning all,
I thought I would let you know I have an alternative to an MSI installer until one can be created. Our company has a program called Lansweeper and in this you can create deployment packages. Although we pay for it, the program can be used for free if you have fewer than 100 assets.
I have created a deployment package for Enscape and tested it successfully and i'm now rolling it out across the office. The attached one is for a silent install to All Users, no Rhino installation, and to the default location.
Hope this is of some help.
