Bummer...

This is darn peculiar. Is the install file that you downloaded = 6.19 MB?
I'm guessing the answer is yes.
Ok, next I'd delete the install file (assuming you saved it first and then installed) and also uninstall the program. Then, download again and install.
If still no luck, do a complete uninstall, take a look at StormJumper's guide in his sig.
[Edit] I'm just noticing you have 20 posts and here I am welcoming you like it's the first time...

I'd like to blame my eyes, but at my age that's probably wishful thinking...
