    "Only a single Instance..."


      I am operating windows 32 bit with Internet explorer and had with no problems until I installed Firefox.  While using firefox, it didn't recognize my flash player and said I needed to install the latest version (  during the installation, it said "Olny a single instance of this application can run".  I tried several times with the same results.  I've searched the adobe forums and tried several of the possible fixes but nothing is working.  I tried to uninstall the flash player and reinstall, but that didn't work either.  At that point, flash player didn't work in Internet explorer or firefox.  I then uninstalled firefox in hopes to just get back to being able to work in Internet explorer.  At this point it is still not working.  Please help.
