i know, there are already several threads on this, but many of them seem outdated, so i thought i'd just start a new one.
We're having trouble installing your McAfee software. Please make sure you have

That URL is, of course, invalid. i've been through two failed chat sessions with McAfee. In the first one, i was told that IE9 had some "compatibility issues" with McAfee, so the technician removed it, going back to IE8. It still failed. The technician then deferred me to Java Support to get Java working again, because at that point, regsvr32 jscript.dll failed.
i did a restore to put my computer back the way it was, hoping that'd mean McAfee and IE9 would be back, and that was okay. Then i went to Java.com, and it said my Java was working fine, so i started up another chat session with McAfee, and immediately escalated it to Tier 2. This guy removed IE9 again, and then tried to re-install it. The IE9 reinstallation failed, so then he told me that Windows had some issues, and i had to go and resolve them before he could help me. So, basically, i'm stuck.
Since that point, i've done an in-place upgrade to Windows, and updated it all the way back to current, with SP1, IE9, etc. Java works.
regsvr32 jscript.dll succeeds
regsvr32 vbscript.dll succeeds.
The install log has this error:

Message: Cannot create a file when that file already exists. (Error code 183)
Perhaps this is a clue?
