I just purchased a copy of Mathcad 6 for Machintosh and I am in the installation process when I met the error message "can't open application INSTALL because the classic enviornment is no longer supported. What must I do? Mac OSX Ver 10.7.4
MathCAD 6 on MacBook Mac OS X v. 10.7.4, need some hand holding to get this installed.
