Reinstallation issue: Cannot reinstall

I tried to install VP today. But apparently in the past I have installed VP and I deleted it manually.

Now whenever I try to install the app, the checkboxs are check and greyed out. If I try to proceed and click next, it gives me a message box “Please select product(s) to install”

What should I do?

Remove the following:

C:\Documents and Settings<user name>.vpinstall.properties directory
C:\Documents and Settings<user name>.vpsdehome.properties directory

Also, check if the above files are present under C:\Documents and Settings\Administrator

If so, remove those files too.
