First do this from an Administrator account, or alter your account to administer your computer.
I can suggest an uninstall (using the uninstaller in the CS5 folder) Check "remove preferences")
Then use the Cleaner tool in Step 3. Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
Download the 12.0.4 update from here Adobe - Photoshop : For Macintosh
And run that update again.
yes, I was doing updates from the Admin Account. My BIG BIG Problem is: I moved to the US recently and had to find out today that my adobe installation CDs incl. all licence docs got lost. I really would have done a total reset of my whole system this morning since I need PSD urgently to work with. And that seemed to be the simplest way to me too. But I cannot do it (((
Looks like I have to find out another workaround.
First if you registered your program your serial number is under the account you used to register it.
https://www.adobe.com/account/my-products-services.html Click on the tiny triangle next to your product to see your serial number.
CS5 downloadable installers are here: Download CS5 products
And if for any reason you can't find it, you have 30 days to use it as a Trial until you can find it.
good to know for the next adobe buy. But for now I didn't register my products can I find my serial number somewhere else?
You can call Customer Care. You'll need some sort of proof of purchase or ownership.
I once failed to register a $35 program and could not prove I qualified for the upgrade, so I had to scan the original cdrom, and they cut me a break.

yes I found the HOW TO FIND MY SERIAL NUMBER link
I purchased the suite in an store in germany and my receipt is gone with my tax docs from 2010. I may give it a try but as I know these guys it won't be work out without the receipt. I have the whole suite on my machine. Isn't there a way to find my serial number somewhere on my computer data? I was crawling my emails for the last 4 years and also couldnt find anything.
