Hello folks,
I have installed and run Dynsim 4.2.4 in 32 Windows XP SP3 successfully without any problems. I don't know if it would work with Windows 7.

In fact most of the technical software would not work with Windows 7 or Vista. If you intend to use any such technical software, I would say have a dual boot system with XP SP3 and I see no reason why you should have problems installing it.

Thanks
