Problem on install with XP and smartFTP

I have used this code for years on W2K, however while trying to install on my XP machine I get this error.

"Windows Installer Installation Wrapper" In Blue box

"The windows installer service could not be accessed. This can occur if you are running windows in safe mode or if the window installer is not correctly installed"

I have installed a ton of stuff on this machine, never have gotten this message before, however I sure can't get smart FTP to load.

Any ideas would be appreciated.
