I had a trial version of Photoshop CS5 and purchased the extended version.
I keep getting all kinds of errors:
DesignPremium_CS5 error -4960
Photoshop_12_1-LS1-3.exe file is all garbled letters
Photoshop_12_1-LS1-3.7z says Safari can't open it
I even tried entering the serial number into the trail version and nothing works.
I have uninstalled and reinstalled tried everything over several time.
Very frustated at this point an over due on a deadline now.
It appears you are using Safari does this mean you are using the Mac OS or Windows? The names of the files you have listed would seem to indicate that you are trying to download a Windows version of Photoshop.
