How can I tell if the PNG plugin is missing? I only have six files in C:\Program Files\Adobe\Adobe Photoshop CS2\Plug-Ins\File Formats and none of them say PNG.

I was called by a friend yesterday with a similar problem. She always saves a copy of her pic with a slightly different name. Suddenly the system stopped putting the .jpg extension after the file name and when she tries to open the file it gives the same error as you got. The icon changes too, it becomes a square white box.

If you can look at the file with the show extensions turned on you might check if the file has a .PNG on it. If it doesn’t do a file rename and put it on.

Then leave the file extensions showing and see if photoshop will save with the file extension or not.

The other odd thing is that if I do a Save for Web I do have PNG-8 and PNG-24 available and they save fine. But opening the same file again with Photoshop generates the original error while opening it in other image editors as PNG works fine.

There is always some jack a** like Richard Sohanchyk who contributes nothing to helping other people an is simply snide and makes everyone angry. What a waste of flesh.

dude hes telling the truth….ive been using photoshop CS3 for around a year now…i upgraded to XP Pro SP3 and it was fine up until about a month ago, now i cant open, save as, or save for web as .PNG

which sucks because ive always used .PNG because of the Transparency support, and unlike .GIF it saves in RGB

so im thinking it has to do with SP3 *freaking microsoft*

If you think it’s involved with the SP3 update, you can always roll back the update to another point in time to verify this.

Just to add to the confusion, We have SP3 installed on several workstations with PhotoshopCS3. None exhibit the behaviour you speak of.

This started happening to me way before SP3 was even released. I haven’t tried reinstalling yet but I’m guessing that will be my only fix. I’m using CS2 BTW.

Odd. Maybe you can use Illustrator to export it to whatever format that your Photoshop can support, while fixing the root problem.

Can you still save .png documents from within Photoshop even though you cannot open them?

Yes I can as long as I do a Save for Web. Save As doesn’t list PNG as an option.

The mode doesn’t come into play since I’m trying to open a PNG.

sorry, misunderstood. the mode doesn’t seem to matter. rgb, cmyk, and indexed all don’t have it.

8, 16, or 32, doesn’t seem to matter.

Hello, I just had the same problem with opening .png’s in photoshop cs on a winxp machine and receiving the "Could not complete your request because.." This coincidentally occurred after I loaded a .8bi plugin to open and save .ico files. Photoshop became confused as to the directory tree. After checking in the PS plugin directory I determined that somehow the directory structure became fongooled and had to be reordered so the the plugins were in the appropriate locations in the directory> Photoshop8>Plug-Ins ->Adobe ImageReady Only ->Adobe Photoshop Only ->Digimarc…etc. This I believe is in the tree structure of the java that powers the Photoshop menus and Windows Explorer API. Anyway after correcting the directory structure my install now works.

The location of the plugins doesn’t matter.
There is no Java in Photoshop.
