I always prefer to use non-installers (.zip files). If your version doesn't work uninstall it and get the .zip version here
http://www.kensalter.com/forum/topic.asp?TOPIC_ID=59 You will have to manually create a profile. From the installation instructions:
"3) Create the data folder. You must use c:\Documents and Settings\<user>\Application Data\FSAutoStart (NOTE: The Application Data folder is hidden, so you must be able to see hidden files)
4) Copy fsautostart_service.ini here
5) Create a subfolder called Profiles
6) copy fsautostart.ini here.
You are now done. You can start FSAutoStart by using fsautostart.exe."
Edit: I just downloaded the .zip file and it has the 2 .ini files. Just make sure you follow the manual installation instructions and put them in the right places. Or you may be able to just cut & paste them into your profile.
