Did the program stop responding during the installation of v. 2.04 or after installing and running the program? We did not change how NV2 installs, if v. 2.03 installs, v. 2.04 should also.

There is something different about WinXP in where it will seem as if the program is not responding but a quick look in your task manager will show it is in deed running. We see this often during the setup of the different windows in NV2.
