"The file archive part of Adobe Premiere Pro CS6 is missing. You need all parts in the same folder in order to extract Adobe Premiere Pro CS6. Pls download all parts."

Hi, I just purchased the download version of Adobe Premiere Pro CS6 online from Adobe.com but I can't download it. I downloaded the file (PremierePro_6_LS7.exe) which I was directed to and tried to run it but a pop-up notification stated "The file archive part of the Adobe Premiere Pro CS6 is missing. You need all parts in the same folder in order to extract Adobe Premiere Pro CS6. Pls download all parts." Problem is, I already downloaded the only other file (PremierePro_CS_6_Content_LS7.exe) but I still get the same pop-up notification. Pls kindly advise, thanks!
