if this is vista you are using (yeah?) - then there is one additional step that you may be missing.

you need to use a command window (--%26gt;Start, type 'cmd' and 'cmd.exe' should appear)

you should run this command window as administrator, so right click on cmd.exe and select ''run as administrator'' and agree to the usual security information.

when in the command window, type the following:

regsvr32 jscript.dll (then press enter)

you should receive a message box saying 'successful'

then type the following:

regsvr32 vbscript.dll (then enter)

if you get another 'successful' message box, then you should now be ready to run the installation.
