can't uninstall IE7 beta2-no uninstall file

I must have deleted my uninstall file for IE 7 beta 2. Now I can't uninstall
or install a newer version of IE 7. There must be a registry change that
will fool IE 7 into either thinking it is not installed or just overlay the
new version of IE 7. I just want to install the new IE 7. It can't be this
hard. ;-)

 

Courtesy of MVP Sandi Hardemeir:

Some software (for example CCleaner) deletes uninstaller directories such as
$NtUninstallie7bet2$ (or $NtUninstallie7bet2p$, for IE7 Beta2 Preview). If
the $NtUninstallie7bet2$ folder is empty, or has been deleted completely,
whether by third party software or manually to preserve disk space, you will
*not* be able to remove the Beta 2 Preview via Add/Remove Programs or the
commandline. If running System Restore does not resolve the situation for
you, then your only choice is to stay with the Preview, or format your PC
and install Windows anew. You will not be able to install any future builds
of IE7 while Beta 2 Preview is installed, nor will you be able to run a
Repair Install of XP.

Hey, PA Bear,
Me again (Krueger). I went to
http://dundats.mvps.org/Internet/InternetExplr/IE_tools.htm] and installed
INET Tools. Unfortunately when I run it (re-installed, ran from severa
locations, etc.) I get the error message:
Line 0 (file "C:\Program Files\IE7 Tools\INET_Tools.exe")
RunWait (Chr (34) & @ScriptDir & "\7za.exe' &@ScriptDir & FixUninstall.zip...
Unable to execute
File name, Directory, or Volume label syntax is incorrect.

I am not that savvy to understand the error message. Sorry to lean on you,
but do you have any further suggestions?
Many thanks again...
Terry
