I have downloaded the offline installer also..but the problem exists. I have gone to all the trouble shooting help and tried everything. but its not worling.. dont know what to do to solve it.
Assuming you've checked to make sure that Shockwave Flash is enabled in IE's addons manager and you do not have ActiveX filtering enabled, Could you check to see if you have the following Windows update installed?
If so, please uninstall it and try Flash Player out again.
Just to clarify, after you downloaded the offline installer, where you able to run through the installation without any errors?
