I apparently have a corrupt riched20.dll or riched32.dll. This is the second time in a row that I can't install new software. I worked with the vendor on the first one and they told me I had a problem with riched32.dll and they can't fix that. I ran Microsoft's FixIt program but it didn't turn up anything. I have a 64 bit Windows 7 PC. Is there a way to get a fresh copy of them... thanks.
