'Cannot be installed on this computer'

I've just paid for and downloaded Parallels Desktop; when I try to install it, it says that it 'cannot be installed on this computer' and to 'make sure your system meets the requirements', but I cannot imagine which it doesn't fulfill. I have tons of free space on a g5 PowerMac.

Can someone help?

 

Your architecture is PowerPC, Parallels Desktop is only supported on Intel based Macs

Next time, be sure to check the system requirements of an app specially since you're running on a PPC and development nowadays tends to get Intel centric.

 

where could I get a good program to run PC programs on my mac in that case?
