I am trying to install CS5 Master Collection (trial). I receive the Exit Code 7, and the error 1402 - Could not open key. I have followed all the suggestions provided by Adobe Support, to no avail. I have run the setup as administrator with full rights. I am installing on a desktop computer, Win 7 64-bit, AMD 64 processor, 6 gigs of RAM, 274 gigs free on a SATA HD. Please help, I am tearing my hair out. I started the day with a full head of hair and am now bald.
Can you please collect the install logs and paste in on the website "PASTEBIN.COM" and provide the link here
To have the install log check this article:-
As Manish said, we need to know which (Registry) key exactly by ways of the install logs. Could be permissions issues, could be blockages from security tools or Windows' system protection...
You may follow the suggestions mentioned in the below article.
In case you still get the same issue, give us the install.log file as already mentioned by Manish and Mylenium.
