thank you so much, Mylenium! I downloaded the file but when I tried to start the installation a window said there is an "initialization error" and maybe it is because of a file not found. It said to download "Adobe Support Advisor", but in the suggested link there is no "adobe Support Advisor"...
if you can help me again I thank you a lot..
ops! I found this suggestion and it seems that it works! thank you again :))
(I have MacOS sierra...)
"Right-click (or Control-click) the installer and choose Show Package Contents.
In the Install window that opens in the Finder, go to the Contents/MacOS folder, and in there, double-click Install. That will open the Terminal application, some lines of code will automatically run, and the actual Installer should successfully launch."
This could be a specific issue with new versions of OS X. You may need to adjust your user settings and permissions on several of the folders so the installer can create temporary files. Beyond that I can't tell you much. My Mac knowledge is too outdated at this point and I can only advise based on what I read elsewhere.
