I'm having the same "Application Error - 0xc000001d" problem. Also running an AMD Athlon with NVIDIA GeForce4 MX video card. Photoshop CS4 runs just fine, but CS5 won't launch.  I've uninstalled and re-downloaded/installed four times, and still have the problem.  Hope you find a DLL fix soon!

Its not true!  SP2 on my laptop work good

Mr. Cox, can I ask why the .DLL error is only occuring on AMD Athlon/Sempron Processors? I am very intrested in computing!

I'm having the same problem and I'm running Windows XP Home SP3, AMD Athlon XP 3200+ 2.19 GHz with 2GB of memory. I'll be installing it on my Windows 7 Ultimate 64 bit with an AMD Athlon 64 machine soon to see if the problem exists there too. I'll keep PS CS2 installed until the issue is resolved.

AMD Athlon XP 2500+ Barton....old processor this is mine. And I have problem with (0xc000001d)

At least you can get it  .  I'm thinking of uninstalling it  getting my

money back.

It is either this May or June that Microsoft will no longer support Windows XP SP2 or below with Security updates. If people want a secure system they should update to SP3. Also SP3 made XP a lot more stable and responsive.

I understand your frustration but I'm sure Adobe will have a fix for this soon.

I hope so.

How long do they (Adobe) give you to ask for a refund?

Hi Herron,

     The reason I bought the new computer and the matching software was to start completely new. I still have my Window 98ME 500 mhz Pentium 2 machine thats 12 years old, and paid only $100 for it. That is where I am coming from, and was using PS4, with Elements 2 that came with my Canon 300D rebel from about 5-6 years ago. I am still shooting with the 6.3 mgb baby but added last year a Canon 10D IR conversion. I do a lot of photo stitching and needed the raw processing power to do all of this in 16 bit before conversion to 8 bit and printing. 64 bit allows for the huge temp files while the image is being created with PTgui.

     The old softwares I had did not have the fine adjustments I read about in the magazines. And I am now taking a beginner photoshop class and CS4 class to get started with all of the added stuff.

     I went from Ok as a Photoshop user to a ignorant child in the new softwares. It is a daunting task to learn this stuff and barely time to eat and sleep while attending college.

     The new HP was a model I found online at Fry's. It was not on display at the store, and they tried to steer me to a model $150 higher. So I had them look up the model I saw online for about $550, 8 gig ram, 750 Gig hd, and the AMD Phenom II, and with the savings I bought a spare 500 Gig internal and got my nephew to install it. This gave me safe duplication of some of the key files along with an external 300 gig drive. The last purchase was a 2 Terrabyte external strictly for archiving. I have yet to get it out of the box, nor add speakers to my computer which I also have now. Not enough time to get everything done. Sigh.

Thanks, Steve.  I'll keep watching.  My old AMD still works fine for everything I do ... except PS CS5 (sigh).

So ... is there a fix? 

May take a while. Lots of testing, and even then, when you think you got all the new

bugs sorted out and fixed, you send it out and someone in another group, sometimes halfway

around the world will come back and say: "WTF are you doing!"

But hopefully not!

yes because AMD 64 has SSE2-3 support

Another one here.

CS5 Works great on my LapTop with Vista and AMD Turion.

Just get the Oxc000001d error message on my desctop using

Win XP with SP3 and AMD Athlon XP2800 processor.

Have uninstall - cleaned and re-installed as per Adobe help desc

but makes no difference.

Help coming soon - I hope.

They're already working on the problem (as has been noted in this thread). It's a PS CS5 bug in which a .dll file is trying to use SSE2 when it shouldn't and AMD Athlon XP and like processors do not support SSE2-3.

I also get the application error too when trying to start Photoshop CS 5 ext."The application was unable to start correctly(0xc000001d) .Click on to close the application"I too have a AMD Athlon Processor. I have installed the CS5 Master Collection.I am unable to start Adobe Encore.I receive an "X Runtime Error" message ! I am also unable to load the Adobe Media Encoder.Getting the message"Processor does not support SSE2 instruction set"I have the same problem with starting Adobe Pixel Bender as I do with Photoshop CS5,application unable to start (0Xc000001d ) Finally Adobe SoundBooth wont start.Not bad 6 applications failing to start/load/work. My operating system is Win 7 on a PC,with all the latest updates and drivers installed. I previously used Adobe Photoshop CS4 Ext,Illustrator CS4,Dreamweaver CS4,Lightroom2.All worked with no problems.I am anxiously awaiting a fix/patch as soon as possible please.All the best from NUGCS5.

I have contacted Adobe and the National Association of Photoshop 

Professionals (NAPP).  I hope someone out there listens and comes up with a  solution

soon!

I'm also  having this problem on an Athlon XP2500+. I know it's an old

processor by  today's standards but still feels fairly zippy for most stuff -

including  photoshop (previous versions which actually work!). I hope Adobe

don't simply  abandon customers who don't feel the, often unnecessary, need to

have the  latest spec machine.

I feel that if this thread becomes long  enough Adobe will have to do

something.

I assume everyone has  registred the problem formally through the support

portal. If not, please do.  Perhaps then it'll be  escalated.
