I mean after all if you have the customer's interest in mind you, at the very least, include an autoarchive option along side the other options. That way when ever I dl, install or update an itemit is automatically archived!
But that option is there.
No its not: The archive application before updating is a backup mechanism. I.E. in case a new version does not work for you you can then have the old version because it was backed up automatically. Although, it makes no sense to allow you to check both boxes as they serve different functions (i.e. you can't make a backup at the same time as you are erasing the backup). If you install a new application (which I just did) with those options checked it will not be put into backup folder UNLESS you manually archive it. Go ahead check it for yourself.
Ideally you should get two folders an archive and a backup folder:
Archive: anytime you dl or install application a copy of the latest version is put in there (so when your sub runs out you have the latest versions of the SW at the time of your sub all in that folder). Since there is a daily auto update function, when combined w/ auto archive, you could be pretty much assured that the latest versions will be in this folder.
Backup: Here you can keep as many different versions of the programs as you want so you can go to an earlier version in case of problem.
This is not the PERFECT solution but it is the easiest and cheapest method for SD to provide CS. You could probably do it all in less then 200 lines of new code.
EDIT: Look most of the stuff is in place. Hell even the archive option is good in that it save the program with the ProgramNameVersionBuild format. SD just didn't bother to put it all together with a couple of more hours of programming. The ISO image would be perfect and that is where digital downloads need to go. Just because SD goes bankrupt and I don't have access to impulse or impulse servers should not be an excuse for me not to have access to what I paid for. This is the part the majority of people are missing with digital downloads and DRM. No matter how good it is now once the compnay is gone so is your investment: no more accessing your music, games, programs, wahtever.
