Flash Player Help / Find version at http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html reports that my installed version is:but Programs and Features (or, appwiz.cpl) reports 11.4.402.267, and so does the .MSI file. What's going on Adobe?
This is a bug with the version string in the MSI package. The actual Flash Player active x control does display the correct version (11.4.402.278). Our internal bug number for this issue is 3333545 and we expect this will be fixed in the next release. I've also posted about this here: http://forums.adobe.com/message/4711264#4711264
