I am trying to install the latest version of flash player and it is not working correctly. When I click on the installer it gives me a window full of code. If I try to open the installer through disk utility I can click on the installer and type in my password. After that the installer window comes up but there is nothing on it. It is just a blank grey screen. I have a mac and am operating yosemite.
I am not familiar with the behaviour you are experiencing. Are you using the shim installer or the full installer (shim installer is about 1.6 MB in size, while the full installer is about 14 MB in size)?
Please provide a screenshot of the installation window with the code using the instructions here, The specified item was not found..
