about incompatible version software fixer

Spent couple of hours but got it to work as follows: 1- Download a program called Orca (http://www.softpedia.com/get/Authoring-tools/Setup-creators/Orca.shtml) 2- right click on mono-androidxxx.msi 3- choose edit with orca 4- Go to InstallUISequence 5- Search for the action name "IncompatibleShellDlg" and edit its condition from "INCOMPATIBLE_SHELL=1" to "INCOMPATIBLE_SHELL=0" 6- SAVE 7- Good Luck. Enjoy!
