I assume you are trying to install a trial version. Follow the below steps:
Error 101/102 normally appear when the the installer is unable to extract the files.
This could be due to a corrupt/incomplete download, the installer trying to extract at a location it does not have permissions to, or just plain permissions issue.
Now it finalizes the download, but gives this error:
Error 101, check for available disc space." I have much, much disc space available, so this is wrong.
when I go to C:\adobe\CS6 Master Collection, there is a completed .rar file
but when I try to extract it I get error
"archive is corrupt."
I did not download to Programs Files.
I have had to restart this download 5 times, due to the program getting stuck at the end of the download, not moving from "download is almost complete, less than a minute," staying there for hours, and then failing. Each time the download fails, I must start the download from scratch, as it does not auto save.
I was really excited about being able to try this expensive product out, before makinga big investment.
This whole experience is leaving me with very bad feelings.
