update photoshop CS6 (cloud)

I am not able to update photoshop CS6 to the latest version. I have this problem on two computers. I get an error message which refers me to a file in the ../common files\adobe\installer directory, but the file is not readable (gz).
I have repeatedly tried to install the update. I have de-installed the program and re-installed it, but am still unable to apply the update. I would appreciate any suggestions.
