- Get the uninstaller (http://kb2.adobe.com/cps/141/tn_14157.html) to
completely remove any remnants of their Flash AX control.
- Disable all [non-Microsoft] add-ons. I usually only disable the
non-Microsoft add-ons. You could disable all add-ons during the
reinstall to ensure that none of them is causing a conflict or
involved in the install problem.
- Install the Flash Player; however, if you had problems with the
on-demand installation from within IE, download the installer
(http://kb2.adobe.com/cps/142/tn_14266.html).
- The Flash Player should now be the only [non-Microsoft] add-on that
is enabled.
- Test if Flash now works. If Flash works, re-enable the other
add-ons one at a time and retest each one.
For future reference, it is best to first uninstall all non-Microsoft
add-ons and reset IE7 before installing IE8. After completing the
installation of IE8 then reinstall the non-Microsoft add-ons.
Adobe's Flash Player is not compatible with the 64-bit version of IE.
Use the 32-bit version of IE. Apparently Flash installs into the
wrong folder in a 64-bit version of Windows so it might not even be
available to the 32-bit version of IE. See the following articles:
