Mac installation says Safari is open, but it is not.

MPBr

OSX 10.8.3

Adobe Flash Player Version 11.7.700.169

Tried to install newest version of flash player when prompted.

Flash installer says that Safari is open and it can not continue, so I check my tasks and Safari is not open. I open safari and then close it with CMD+Q to ensure all instances are closed. This does not work.

Restart my computer to ensure that safari isn't open. Attempt installation again with fresh restart. Flash installer says that Safari is open and it can not continue.

Can not install newest version of Flash, nor can I locate information pertaining to this issue.

Any help is appreciated (assuming that it's not a problem with the latest installer which will be remedied shortly).

Thanks
