This has nothing to do with Adobe. You really need to talk to your computer's admin/ owner/ primary user and get the pertinent permissions.
I'm getting the same thing. The problem I haver is that I AM the administrator and the only user account on my computer....
Seek out documentation that describes the infernal "User Account Control" (UAC for short).
You may be a member of the Administrators group, but you do not normally have Administrative privileges. Honest.
What you do to get administrative privileges is to start the program that needs them via the right-click context menu, selecting "Run as administrator". Note, for example:
Thank you. Somehow I managed to get it downloaded by trying it 3 times, restarting my computer, checking my privileges (lol), and updating creative cloud. But thank you, that is good to know.
Background - Installing under Windows 7 from Photo subscription
Problem - failure some way into the download process with the message that the next stage requires administrative privileges
What's it got to do with Adobe?
This has a lot to do with Adobe. Standard MS security practice is use a user account with minimum privileges for all normal purposes - such as running e-mail. In addition, the "Administrator" account login is disabled by default and the expectation is that the machine will be managed by a different account with user privileges. The Adobe acceptance e-mail will normally be loaded into the user account where the e-mail client (e.g Outlook) is accessed. Following the instructions on this e-mail will lead to the install being attempted into the user account with minimum privileges. Every other recent application I come across will request a password of an admin account to proceed with the install in these cases. Adobe's install just dies with its unhelpful message.
It's actually worse than this, since Adobe require that the download takes place into the administrator account - as you need to enable login first. (Run as Adminstrator does not seem to be an option with the download process, as the executable file is not obviously available to run)
When you are on a relatively slow connection (as I am.. 2.3mb dowload) the need to work through this is a bit tedious. Things now seem to be working, but its the third iteration.
1. Follow the instruction on the acceptance e-mail and click Get Started to get the web screen up in the user account. Copy the web address this generates from the top left of the browser (highlight and press <Ctrl>+C). Paste this into a text file - save to a stick or an area of shared storage. Exit the browser and account.
2. Enable the built in Administrator account from your management account (see How to enable and disable the Windows Administrator account for example. Make sure you give the account a suitably complicated password but don't rename it. (you'll disable the login anyway when you've finished)
3. Exit the management account and log in to the built-in Administrator account, which will now be available. Go to www.adobe.com change your region if necessary, (bottom left hand of screen) and log in, ticking the keep logged on box. Open a new browser tab and copy in the saved web address from the acceptance e-mail. Things should now work (well they seem to be working for me, anyway.., though I am not sure how Adobe will handle things if the program download fails because of comms problems (1.5 hrs for 38% of photoshop)
4. Remember to disable login to the built in Admin a/c when you finish.
A better solution
Adobe to take account of the above when putting its load routines together.. at the very, very least provide some warning and instruction on the acceptance e-mail.
BW to anyone who picks this up & good luck
