Today I finally installed the Dimension Pro!! Wow!
I think I should report what I did.
My Mac is sold in USA and I bought it.
But you know the Mac OSX can change language environment.
And I'm using in Japanese lang.
The solution is....
I tried to back to English environment on "System Preferences" of OSX.
And I logged out once and then I logged on again (not necessary reboot).
And tried to install the Dimension Pro.....
OMG I could input SERIAL NUMBER finally!!!
I think I can back to Japanese lang environment when installation is done.
(Actually the installer is working on background now! so I'll try this after completed)
But I never had like this problem. Everytimes I could install any softwares...
OK, so for NOT english native people (like me), If you want to install Dimension Pro(Maybe only Mac?),
you have to back to English environment before.
But I'd like to say... Cakewalk doesn't realize this problem.
And the support replying is not supreme fast.
Because it's assumption of all customer is using English environment...
I hope you check the software on many language environemt such as
Japanese, Chinese, Germany, French, Spanish...
Because you are the one of world software maker!
Anyway, thank you very much and I'll have fun with Dimension Pro soon.
(Yeah still installing on background)
