Pawan,
(Although I replied you in another post, just replying here once again so that people searching this issue would find solution)
Root Cause:
Flash update released on 12/28 as 20.0.0.267.
Solution:
Downgrade to earlier compatible version of Flash
Resolution Steps:
1 If you previously installed a later version of Flash Player for Internet Explorer, you will be prevented from installing an earlier version.
So, download 'Uninstaller for Flash player" from below link:
https://fpdownload.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe
This deletes the "safe versions" registry key by default.
2 Exit all browsers and other programs that use Flash.
3 Run the uninstaller.
4 Download 20.0.0.228 (released on 12/8/2015) from below Archives URL:
Extract and install "flashplayer20_0d0_228_winax.exe" (for ActiveX)
*** Set auto-update option to Off during installation itself.
