This problem has been the case on many applications & websites over the past 8 months, which renders much of the web and some of my software, useless.
I have followed all recommendations, from MS, Adobe and from suggestions on many, many forums, yet still the problem of installing the FlashPlayer update continues to hamper my Windows experience. I have been FORCED to use Chrome as my browser instead of Internet Explorer and now my printing software from HP no longer works.
The ActiveX control/Update from Adobe will NOT under any cenario, complete installation and continues to fail when registering. I am using admin rights and I am very competant with the use of computers and software. The only thing I am reluctant to do, is to manually edit the registry.
Searching the net, I find this is a very common issue which is yet to be resolved. Why is this? The installation of any software in this day & age, should be straight forward and simple. This issue has been a problem for thousands of people for quite some time and I am dismayed that it has continued!! Why have Microsoft & Adobe failed the end user in respect of this?
I have tried all previously suggested options and procedures set out here, on the Adobe website and those recommended in forums. I have also tried the option to un-install Flash Player (with Adobe Flash Un-installer), and re-install from scratch. I do have full admin rights on this PC and have run the update as Administrator. I have - before someone should ask - followed the install procedure with all security software disabled.
So sensible people, with sensible answers, how did you fix this issue on your machine?
(OS: Windows 7 64bit, IE 10 - Latest - also now have to use Chrome to view online video content).
'Failed to register' is caused by inadequate/corrupted registry key permissions.
One possibility to fix it (does not work in some cases): How do I fix Windows permission problems with Flash Player?
Another possibility that I have just though of: can you try http://support.microsoft.com/mats/program_install_and_uninstall/
Also, have you tried to use the offline installer from http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html#mai n-pars_header ?
