No software is free, i should know, because ive written individual programmes for barcode scanners.
Software for whatever application takes considerable time and effort to develop and get right for its intended use.
When the user downloads the Viewranger software, they are given permission to use that application for a set number of times, that's what licence keys are designed for.
If anyone here is under the apprehension that the Viewranger software is free, then they know little or nothing about software development.
I designed my own and in conjunction with my partner, wrote and designed individual software applications, for different bar code scanners.
No software is free, the user somewhere down the line has to pay to use it, when their licence key has expired.
How on earth does the likes of Microsost and Apple make billions in revenue from their software, if they designed the software and allowed everyone to use it for nothing, they would be soon out of business.
