1. If you installed IE8 Beta 1, then installed Vista SP1, and then installed
IE8 Beta 2, you're right: You won't be able to uninstall IE8 Beta 2 or IE8
Beta 1 without first uninstalling Vista SP1.

2. If, however, you installed Vista SP1 without having installed IE8 Beta 1,
you will be able to uninstall IE8 Beta 2.

If #1 is the case, the only good news is that you'll be able to install IE8
Final Release.

Back to your problem, please answer the following by number, not inline...

1. Does disabling (or even uninstalling) Comodo Firewall AND THEN enabling
the Windows Firewall allow KB955302 to install?

2. Are you getting an error similar to "configuring updates stage 3 of 3. 0%
complete"? (cf. http://support.microsoft.com/kb/949358)

3. Did you install Vista SP1 via Windows Update or manually?

>>> Comodo 3 FW (v.378)
>>> AVAST HOME EDITION v. 4.8.1229
>>> SpySweeper v. 5.8 (build 55)
>>> ST, SAS, A2antimalware on demand scanners
>>> SpywareBlaster 4.1

4. Were all of the above fully disabled (including "real-time protection"
components/services of all anti-spyware applications) and was the Windows
Firewall enabled when you installed WinXP SP3 and/or any IE8 Beta build?

>>> Contacted the microsoft support without success.

5. Explain.

Unlimited installation and compatibility support for Vista SP1 is available
at no charge through 18 Mar-09. Go to
http://support.microsoft.com/oas/default.aspx | select Windows Vista |
select Windows Vista Service Pack 1
