I've been trying to install Adobe Reader for 2 days now and no matter where I go to try and install it I keep getting the same error message. I'm running Windows 7 and all my updates are updated so I'm at a loss here. I need to install this bad in order to read some of my emails for work. When I get the error message and go to click no or the X to close the window the window behind it says "undefined"...I'm attaching both pics so you can see what I'm talking about and hopefully you can tell me how I can fix this and install it. I'd appreciate any help you can offer.
