How to see inside an "EncryptedScript"?

[Peabody]

This is a long shot, but maybe sombody can help. If it
matters, I'm running IE6.0-SP1 under Win98SE.

I subscribe to a service called WebcamNow, which includes a
voicechat feature. In the past, new voicechat plugin
versions have downloaded and run just fine, but the latest
version errors out during the install. The downloads appear
to work ok, but then the installer apparently tries to
register a .dll (extracted from the .cab) that isn't in the
expected folder. I'm trying to go through the html and
scripts in the downloaded files to see if I can figure out
what's going wrong (support is a robot and is no help).
Another plugin from that site downloads, installs and runs
just fine, so I kinda suspect this may not be my fault.

From the error log it appears the problem may occur when
a file called voice-installer.js is called, but the script
in this file is encrypted. I've reproduced the contents of
the file below.

I just told you all I know about javascript, so I don't know
how the decryption would work. I also don't know what the
rules are about decrypting, but this is a completely free
feature, so I don't think there's anything particularly
proprietary or valuable involved. Bascially, I just need to
know what the script says so I can try to figure out what's
going wrong.

Any help would be appreciated. And I should say that if
any true expert out there has some free time :-) and would
like to help solve this, I could zip up all of the
downloaded files, the error log, and the INCTRL5 report and
email them to you. The html and this .js file ae pretty
short, and I suspect the problem might be readily apparent
to someone who knows what he's doing.

Anyway, as I said, any help or suggestions would be
appreciated.

You know, "something" is not working, your educated guess is, a .dll
registration issue, which could be permissions or registry or who knows,
now, what that "something" might be, is really up for grabs.
