Invalid Serial Number going from CS to CS 4

Have Photoshop CS on my Windows 7 computer, trying to upgrade to my purchased (by me) CS 4 upgrade. The install accepts the serial number of the CS 4 but says the CS serial number is "invalid" though when installing the CS the serial number was ok. CS software was also purchased by me in 2004.

Acrobat 8 - switch hw and os from win xp to win 8.1 - installation says 'invalid serial number' - although I am very sure, it is :o)

Hi folks,
I am switching from my former pc (win XP) to a new one (Win 8.1).
As I wanted to move my acrobat 8 installation to the new computer, I did the following right now:
- I deactivated the license (from within acrobat 8) on the old computer
- I uninstalled acrobat 8 on the old computer and restarted it
- I downloaded acrobat 8 from the adobe website on the new computer
- I startet the installation, which asks for the serial number
- I logged in to my acrobat-account and found my serialnumber there
- I checked this serial number with my paper-copies and invoice (bought ion 2007): it's allright
- I typed in the serialnumber / I copied it in from the account / I copied it from the email I recieved in 2007 / I checked it twice and more:
The installation-tool says 'invalid serial number' - although I am very sure, it's the right one.
I cant go further.
What is going wrong or am I doing wrong?
thanx for your help

Hi crunchycrisp,
First of all i wont suggest you to install Acrobat 8 on windows 8. This version of application has never been tested on Windows 8.
You may upgrade to the latest version of Acrobat.

Invalid Serial number during upgrade from 10.4.11 to 10.5

I upgraded our Xserve from 10.4.11 to 10.5 and when it first boots after the install, I get to the enter serial number screen. At this point the 10.5 serial number I enter goes through validating and then says invalid serial number format. I have several serial numbers I have tried so I know that a wrong serial is not the cause. I have tried connecting from another computer with server admin and changing the serial number that way, which when, I do shows the 10.4 serial number but then says invalid serial when entering the 10.5 serial. It seems like it is confused on what the serial number or format should be. Is there a way to manually install a serial number or at least get past it so I can then install the most recent update and hope that fixes this issue? I see there were some similar issues with the 10.5.8 update but I think the install dvd is only 10.5 or 10.5.1 maybe.

Well I finally got past it by ssh'ing into the server while it was at the serial number page and issuing it this command and specifying my serial number
/System/Library/ServerSetup/serversetup -setServerSerialNumber xsvr-xxx-xxx-x-xxx-xxx-xxx-xxx-xxx-xxx-x
I then rebooted the server and it came back to the same enter serial number screen but upon entering it one more time, it validated and is happy now.

I am trying to reinstall CS3 from a download I bought several years ago, and it is saying my serial number is invalid. I am taking the serial number directly from the list of products on my Adobe account. Please advise

Uninstall and try the Adobe Creative Suite Cleaner Tool before reinstalling - it helps resolve installation problems for CS3 thru CS6 and for Creative Cloud

Hi Rosera,
This is bad and I am sorry to hear that you are running into these issues.
Let me connect with you, so right now, the current state is that you have installed copy of PSE 8 in trial on your windows 7 machine, and when you are trying to enter the serial number from your PSE 8 Box, it is saying the serial number to be invalid?
It might sound pretty obvious, but please make sure that you are entering the serial number correctly and of PSE 8(in case you bought a PEPE box)?
Have you tried the steps mentioned below by Barbara?
If possible, you can send me the serial number through PRIVATE MESSAGE and I can check it on my end that whether the serial number is indeed invalid or that the issue is with your machine?

Ankush

I see that the number in my Adobe Account is a MAC serial number – I purchased both the Mac and Windows versions of the program. I tried to enter the serial number of the Windows version into my account and it says it’s already registered. But when I installed the Windows version on a Windows computer I got the invalid serial number message. They have two different serial numbers! Can you help me with this?

I cannot install a previously purchased version of acrobat 9 pro downloaded from the site. Returns message at final install steps "invalid serial number." I had copied it and pasted it directly from "My Adobe". What to do?

Find your serial number quickly

I keep getting an invalid serial number when re-installing Adobe Acrobat 9 I am getting my serial number from my registered products

If it was an upgrade version, it may be you are being asked for the qualifying product S/N and are entering the new S/N instead. That would cause a problem.

Says invalid serial number-i got it via email from adobe. (CS6 design standard student edition).

I think that you'll need to get in touch with support to sort this out.
But you could check your order to see if you ordered and upgrade or a new purchase. The serial numbers for upgrade are different, and require the earlier version on your computer ( or its serial number instead).
If you've oredered an upgrade, check that you're entering the correct serial number. You'll probably be prompted to enter both: once for qualifying product and once for the new upgrade.
Let us know if this was the issue. If not, I suggest that you get in touch with Adobe Support.

Adobe Photoshop cs4 extended invalid serial number

I just bought adobe photoshop cs4 extended from a large retail computer store.I had the trial version of photoshop cs4 extended.I uninstalled the trial version and installed from dvd.I got a Invalid serial number error.I am sure there was a software configuration problem .The reason ,the disk needs to verfy that you have the original disk,If that happens ,After installation ,Just delete this file C:\Program Files\Common Files\Adobe\Adobe PCD\cache\cache.db This is the location where it installed the serial . After deleteing it will create a new cache.db file and store the serial there that goes with that disk . When you open PS cs4 it will ask to enter serial again.Just enter the serial again that came with box ..I guess this would work also with adobe photoshop cs4

I encountered the same problem with Photoshop CS5 - I had the trial version installed, and now bought the extended version, but it keeps saying the license key is invalid. I did unistall, ran the cleanup tool, but it is still not working. Any help is appreciated.

Acrobat 9 Pro reinstallation gives message "Invalid Serial Number".

I just successfully deactivated a copy of Acrobat 9 Pro, insuring twice that I had accurately recorded the serial number. Now, when I attempt to install it on another computer, I get the message "Invalid Serial Number. This is not a valid serial number. Please go back and re-enter your serial number." This is going on a new computer for a staff member who needs the functionality of Pro so it is a big deal.

Dave;
Short version – it stated with 9707 – however the ORIGINAL SN did start with 1118 and now mysteriously works.
Long Version – About 2 years ago, one of our attorneys left the firm. We had purchased and installed 9 Pro on his PC while he was here and deactivated it on his computer when he left. However, when we went to install it on another PC, we kept getting an invalid serial number message for the original number beginning with 1118.
Adobe tech support at that time gave us a number beginning with 9707 and it worked. The computer it was installed on at that time is circa 2004 and is being taken out of service. However, with 9 Pro still being a product that meets our business needs, we saw no reason to dispose of it and deactivated it. When we went to install it on a new computer, we got the invalid serial number message on the 9707 serial number.
Yesterday, I dug the original cd case out of a box and entered the original serial number beginning with 1118 and this time it worked. I know it was the correct box (out of our 20+ licenced copies of Acrobat) because it still had my notes from my tech support call including the 9707 serial number.
Bottom line is that this issue appears to be solved now (he says with all 14 of his fingers crossed).
Thanks for emailing me though.
Kind regards,

Acrobat 9 Professional - Invalid Serial Number

All, having issues with installing Acrobat 9 Professional on a Windows 7 Enterprise workstation thats going to be used as a baseline build. Downloaded my software from the my Adobe account from licensing.adobe.com, and my license info as well. The software can be installed on an XP machine just fine. With this Windows 7 build I'm working on, I get the "Invalid Serial Number" error. I believe previously there were older versions of Acrobat on this build but I removed them all and cleaned up the registry as well. Could there be something that I'm missing that Acrobat 9 is seeing to bring this error? I was able to install our copy of Acrobat 8 Pro just fine. Other pieces, this machine is not on the network yet, and my copy of Win7 hasn't been activated yet (because of it not being on the network). What else can I check for? It must be seeing something on the machine for it to be popping up with this error. Somebody told me, if a previously licensed Acrobat copy was installed, it could show this message, but I don't see a trace of any file or in the registry. Help!!!

Just to add. This is a volume license of Acrobat 9 Pro. Not part of a CS bundle or anything like that. No other Adobe software installed except for Flash Player.
