I am using Origin 7.0 SRO. I tried fitting data using the non-linear curve fit toolbox. However,origin stalls everytime I open the non-linear fit toolbox. Does anybody have any suggestions?
Origin 7 is not supported on Windows Vista or Windows 7, if that is your OS.....Origin 7 was released way before those OS versions.
So please try the 8.5.1 demo and then consider upgrading. If your OS is still WinXP, then contact tech support so they can see what the problem could be.
