I recently purchased a new laptop that does not have an optical drive. As such, I have downloaded the two files from the Adobe site (Download CS5 products) several times. For some reason, the first file set cannot be extracted. It is in 7z format and I downloaded the 7z software to extract the files, but it continues to be unable to do so. I have placed both the 7z and exe files in the same folder on my desktop so the fact that I cannot extract the installation files is confusing. What am I doing wrong? Please help!
