Hello,
In that we recommend you try our advanced automation software, Automation Anywhere 4.0. It has a very powerful feature to convert your tasks into independent executables that can run on other machines without requiring to install the software.
To make it work on different resolutions, what we suggest is, use the advanced option in the Mouse Click command and make it relative to window as opposed to screen.
Also, if you can record your macro in the lowest resolution then it should work in all the higher resolutions.
You can download the Free trial of Automation Anywhere from
