When I try to install the 3.9 sp1 VPN client on Vista I get a Microsoft
Windows message stating "Setup.exe has stopped working. A problem
caused the program to stop working correctly. Windows will close the
program and notify you if a solution is availalbe". Of course, Windows
never notifies me of anything. Does anybody know what is causing this?

This is on a Toshiba Satellite A205 Notebook with a 1.73GHz Intel Dual
Core processor and 2GB of RAM running 32 bit Vista Home Premium.
