This is quite a niche software, and requires a continuous internet connection. However when I package it with Cameyo, OpLap refuses to run and writes to an error log file. What it should do is open up a dialog box to enter my product key and email address. I should add that the portable version does not run on the machine where the program is installed on either. The reason I require a portable version is so I can run it on computers where I don't have admin rights to install the software.
Unfortunately with any of our software Admin rights are required to install. Once it is installed and the user has read/write access to the 'RoamingAppData' for the local user it can be run without needing Admin or Internet Access.
I'd be happy to talk about this in more detail if need be as we have recently had it installed on school computers for users without Admin rights and everything seems to be working fine.
