Installers for Flash Player and Acrobat Reader not visible/stuck.

I am running a windows 7 64-bit computer. When I run the installer, no installer window appears. I do however see the process in the task manager, and see that the installers have been moved to my C:/../AppData/Local/Temp folder; however, after that point the process seems to stagnate. How do I fix this? Is there some file that the installer requires? There is no error message for me to troubleshoot this on my own. I've restarted my computer multiple times, have everything else updated, and run the most current version of mozilla firefox. Help would be greatly appreciated.
