Incidentally, CS4 hasn't been supported by Adobe for years.
Posting about it is futile.
Also, this is a user forum. You are not addressing Adobe here.
I couldn't find any option to edit my post. I feel like a noob.
Which Adobe Photoshop version are you using. If it works in newer version then I will deffinately upgrade to newer version.
Just let me know if it works or how to make it work.
Here is the original PNG file.
And I apologies if I did any wrong.
No need to apologize at all.
You cannot edit a post once someone has replied to it. That's normal.
I happen to have every version of Photoshop installed, since Photoshop 7.0.1 through 13.0.6.
I don't see any problem opening your image on any of them, and that includes CS4 v. 11.0.2.
I assume that the very first image in your original post is a screen shot of what you were seeing; logically, it opens the same in any version.
I suspect whatever issue you are seeing is specific to your machine.
What exact version of CS4 are you using? If you are not on 11.0.2, you should update it ASAP. Be aware that the Adobe auto updater was so unreliable and useless, you will need to download and apply the update manually yourself. Do not rely on it at all to tell whether you are updated or not. Look at your splash screen in About Photoshop.
You have not given us any details about your system (see next post in this regard), so I cannot give you precise guidance yet as to where the download is located. I don't even know what your platform is, Mac or Windows.
Note that because this is boilerplate text, not all points may apply to any given, specific poster.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
someone may be able to help you (not necessarily this poster).
a screen shot of your settings or of the image could be very helpful too.
Please read this FAQ for advice on how to ask your questions correctly for quicker and better answers:
I have found the solution. It was problem in my adobe photoshop cs4. I don;t know the exact version of it as I have uninstall it.
Today I have downloaded Adobe Photoshop CC 20140508.r.58 and it's fix the problem. Now I can open those kind of PNGs without any problem.
Thank you versy much for replying.
