RATS ! Adobe went out of their way so people could not steal their software, but at the same time they made it hard for people switching computers down the line ! However, when I plugged in the serial number I was 4 figures short ! The first 4 digits were missing from that serial number. I got a list of parameters including the Serial Number. I went to the Help menu and clicked on SYSTEM. Unfortunately, Only the trial-key was embedded on the XML file, no sign of the real key ? I then connected my old computer which has Photoshop CS5 and Lightroom on it, to my Monitor and started up Photoshop.

Then I tried going to the 'application' file to see if the key was embedded in the start-up XML file: C: Program file/ Adobe/ Adobe Photoshop CS5.1/ AMT/ application 926287053123815334279360 I tried several things such as downloading a set of keys I found on the web, but none of them worked. Of course if I had the original sleeve I wouldn't be calling them ? They said the serial number is usually on the sleeve of the disk it came with. The reason why I stuck with Windows 7, is that some of my hardware, printer, scanner etc will only work on Windows 7.Īnyway, I was tying to transfer Photoshop CS5 and Lightroom to my new computer, when I realized I did not have the original serial number ! I called the folks at Adobe and even though I showed them a receipt with a transaction number and account number they said they could not find the serial number, because it was not registered with them. Sometimes 10 or more times per day ! Finally I decided to replace it with a Windows 7 Dell computer I got off Amazon. The computer worked fine for several years after that crashing only once or twice a day, but lately it started crashing again. After sending this computer back to the manufacturer several times and spending hours on the phone with HP customer service due to the crashing problem, I thought they/we finally had it fixed.

This computer is a Hewlett Packard(HP) 'Elite', which was state-of-the art when it came out back in 2009. I have an old windows 7 computer that kept crashing on me several times throughout the day for no obvious reason.
