Upgrade CS4 to CS5 with invalid serial number from pc to mac

I bought CS4 from a registered reseller a while ago, but now when I try to register the download, it says the serial number is invalid. I am now unable to reach the reseller. I have recently moved from pc to mac and would like to purchse CS5. Is it worth trying to register the CS4 so I can qualify for the reduced rate to upgrade to CS5? Or does the change from pc to mac mean I need to purchase new software entirely and pay the full rate?

If I am right , you are planning to buy the CS5 hence the article given by Mylenium would not help as Adobe provide the platform swap for the latest version.
You have to contact Adobe ....They will check the serial number of the CS4 is valid or not....and will register for you.
Once registered you can straight away place the order for the CS5 on the discounted price for MAC , there will be no problem weather you have the cs4 for mac or win
You should be bothered for your CS4 serial number because if you buy the upgrade of CS5 , when you will install the product it is gonna ask you the cs4 serial number .....hence get the serial number checked otherwise you have to buy the new software entirely.
Everything is dependent on CS4 serial numbr, buying CS5 is not the problem....you should have correct serial number of cs4 , get it checked.

Problems with Invalid Serial Number

I had a hard-drive failure last week, bought a new disk and had to reinstall all my programs including Photoshop CS4. I entered the serial number from the back of the box that had worked on my computer for years only to get the error message "Our records show that the serial number used to set up this software is invalid." It then shows the exact same numbers I have on the back of my box - no typos - "This serial number will no longer permit you to use the product."
It then gives me a helpful link where I can buy a new serial number online. I already paid for this product once, so isn't that extortion? Any hints or help on how I can get going again without having to put up more money would be really helpful.

Thanks for the link. I did see if entering the number without hypens would work (it had boxes, though, that precluded the hyphens, and I checked on the other problem scenarios, like platform or having a bulk license. Unfortunately I am still stuck...

I am trying to "personalize my cs2 software online download with the serial number from my original boxed cd set and it didn't work. I tried using the download serial number and that doesn't work either. Need help!

I am trying to "personalize" my cs2 software online download with the serial number from my original boxed cd set and it didn't work. I tried using the download serial number and that doesn't work either. Need help!

I understand that you have also used the download link & serial number from Adobe - CS2 Downloads, if still the CS2 is not working, then please refer to the system requirement for e.g System requirements | Photoshop
The issue can be that the present operating system might not be compatible with the CS2.

CS4 Acrobat 9 Pro invalid serial number

I have Adobe Creative Suite 4 Master Collection Student Version. I bought it back in 2009. I recently uninstalled everything except Acrobat 9 Pro because I wanted to keep it. I opened Acrobat today and it asked me for a serial number. I typed in the long code that was printed under the "Product Name" on my paper with all of my information, but it said that the number is invalid. I researched and found that a student license NEVER expires, so what's the deal? Another spot asked for my "Coupon Code" saying that it started with 5 letters and 17 numbers, but my coupon code is "8Z24-....." Please help me.

I managed to clean my registry, then reinstalled Acrobat 9 Pro using the Master Collection discs and succeeded. But, now it is giving me crap about "Product is part of a suite and must be opened after opening another program, such as Photoshop." Are you kidding me? I did NOT install anything except Acrobat 9 Pro. However, a few other programs managed to sneek themselves in: Mocha for After Effects CS4, Distiller 9, and LiveCycle Designer ES 8.2. I'm pretty sure that I did NOT check mark the boxes for this crap, so I don't know why I now have it. I'm really thinking about uninstalling the whole thing and just using the trial version of the new Adobe Acrobat XI Pro, for 30 days, of course.

Bought Aperture 3 Upgrade. Won't accept my Serial Number from Aperture 2...

I have Aperture 2 and my Aperture 3 Upgrade will not accept the serial number no matter how many times I try it. Please help. Why the he11 doesn't Apple have easy contact numbers for situations like this?
Thanks.

I assume you are entering the characters correctly with all letters in uppercase and all dashes included. If so, I’d call Apple.
By the way, before I upgraded, I renamed the version 2 Aperture program Aperture 2.1.4. This way when I installed my upgrade it created a new version 3 Aperture program, “Aperture”. I wonder if following this technique will get around your problem with the version 2 serial number.

Adobe Acrobat 7.0 Professional won't install with new serial number from Adobe

Having replaced my PC I tried to install Adobe Acrobat 7.0 Professional but I was unable to activate registration as it had already been registered and is an 'old product'. I have contacted the Adobe on-line advisor and was given a new serial number and a file to download.
The set-up wizard will not complete even though I type in the new number accurately and each time I've had to abort installation as it says it can't be verified.
Does anyone have any suggestions or explain what I might be doing wrong please?
Thank you

Thank you Bill for replying.
I have been able to install the disc but it tells me that I have to activate it with a time limit of 30 days and counting. Activation fails each time I've tried. As I'm nearing the end of the time limit I decided to contact Adobe for advice. They gave me a download package and new serial number but it's only suitable for OS XP and Windows 2000 so I'm unable to download it. I was told by the advisor if I still had problems to use the forum as a means of support so that's why I'm talking to people here.
I have uninstalled Adobe Acrobate Pro 7, so I might try reinstalling the disc to see if it gives me another 30 days grace, that, at least, would be a way around it.
I'll now follow the link you've given me. Though I do suspect I'm in a bit of a cul de sac.

How to get MAC address list and HDD serial number from Windows and MAC machine?

Hi,
I'm developing a AIR application. I'm implementing the product key mechanishm. I need to identify the users' machines uniquely. I chose MAC address would be a better way. But a computer has list of MAC addresses including LAN card and Wi-Fi card addresses. So, I need to get the list of available MAC addresses from the computer and the Hard Disk Drive's serial number. HDD serial number would be helpful to cross verify the identity.
I'm able to get the MAC address using NetworkInfo class. But I need to get a list of available MAC addresses and HDD serial number.
Is there any classess to accomplish this task?
Thanks in advance.

See if this link can be of a little use to you.

I cannot register photoshop cs4?! Getting invalid serial number message and I've owned this product since 2010. Also shows in my products on the adobe website.

Title says it all, and I can actually speak to a person at Adobe to get this cleared up! I unregistered the photoshop before uninstalling Web premium.

There is only that one number as far as I know. You need to get someone there to help Adobe Support is far from what it should be. Having to use Adobe support has never been easy or pleasant. However they have help me activate Photoshop after a couple disk crashes for there is no way for users to deactivate versions of Photoshop activated on the crashed disk.
I notice your serial is for the Web Premium suite not just Photoshop CS4. Are you installing the suite or just Photoshop CS4 I have only installed Photoshop myself. I do not know if there is a difference in installer between Stand alone Photoshop CS4 the Suite Photoshop CS4.
There surly is a difference in size of the downloads,

Any Invalid Serial Number Installation Issue With PSE 12 - PE 12 Windows or Mac ?

http://forums.adobe.com/message/5711110#5711110
Today I went from Photoshop Elements 12 and Premiere Elements 12 tryouts to the purchased boxed versions that came with two installation discs. One of the discs was for Photoshop Elements 12 and Premiere Elements 12 Windows and the other for these versions on Mac.
On Windows 7 Professional SP1 64 bit desktop computer, I was hit with Invalid Serial Number for the installation of Photoshop Elements 12 which I did first. Tried 4X, double and triple checking to make sure this was not "user error". It was not. On the 5th try, the purchased serial number was accepted and the installation went to a successful completion.
Tonight a friend alerted me to reports of similar happening for a lot of Photoshop Elements 12 Mac users. See the link posted at the top of my post.
At no time did I see this problem with Premiere Elements 12 installation from the same disc as for Photoshop Elements 12 installation.
Afterward, I installed these programs with the same installation disc on my laptop computer Windows 8 64 bit, I did not have any problems with either installation.
At this time, I do not know if this Invalid Serial Number is elusive to Photoshop Elements 12 or not.
If anyone is experiencing this problem with Premiere Elements, please let us know.
From the link above, it would appear that Adobe is working on the issue.
Thanks.

Thanks for the reply.
In my case, I had the network firewalls and anti-virus disabled when I did the installs of Photoshop Elements 12 and Premiere Elements 12 on Windows 7 64 bit as well as Windows 8 64 bit.
I was fortunate in that a 5th try of the serial number entry for the Photoshop Elements 12 install on Windows 7 64 bit was successful, so I did not have to do the computer restart and retry of the install with the purchased serial number. But, good to keep in mind, just in case.
It is ironic...last time around I got caught up in the Shared Technologies issues with Photoshop Elements 11 and Premiere Elements 11 on Windows 8 64 bit, not Windows 7 64 bit. But, in that case, I did find my way eventually to a successful install on Windows 8 64 bit. This time around it was Windows 7 64 bit where the glitch occurred, but, for me, only for Photoshop Elements 12.
But, could you clarify...are you generalizing that Photoshop Elements 12 Mac Invalid Serial Number is due to server issues and Invalid Serial Number encountered by Photoshop Elements 12 Windows is "online - due to some firewall or network issues"?
Just getting prepared for if and when more questions on Invalid Serial Number might pop up in this forum.
Thanks.

I have Acrobat Pro 9 with the serial number. How do I stop the error that will not allow this?

I have lost my hard drive three times and now my Acrobat Pro 9 will not activate with my serial number because it was an upgrade and the error wants the serial number from the previous version. I do not have this information. Please advise, I only have 6 days left before I am locked out. Thanks.

Hi,
Please contact Customer Care at 8008336687 and they would be able to unlock the serial number for you.
Since you said you owned a previous version and you lost the serial number, you can log on to your Adobe account online and check for purchased softwares.
Else if the software was registered the support agent would be able to retrieve that information with the email used to register the software.
Regards,
Ravi.

I take a screen with invalid serial number at the left corner and after that nothing, blank screen. When i go to bios i see that there are no infos about hdd, cs, motherboard serial number etc, so i cant boot from usb. I also delete the recover section on my hdd and i cant run recovely.
I reinstall the bios but nothing. Any soloution?

Hello dskal
Thanks for posting on the HP Forums!
I understand you are experiencing an issue with your notebook. However, since this is a commercial notebook, you should post your issue on the notebook board of the HP Enterprise Forums for a better answer.
