So, a few years back my sister got the Adobe CS4. Would it be all right if I, being her sister in the same household, installed it and used it on my computer? If not, is there a way to purchase a special license or something for that? She told me she was not meant to share it with anyone, but do family members count, especially considering the fact that the program is outdated?
You can use it on two computers at any one time. I really doubt it would make much difference to Adobe, but it is a gray area. The only way to know for sure is to read the terms and conditions thoroughly.
