I just installed Photoshop cs4 on my new laptop, a Lenovo Y510p, and it refuses to open any and all .png files. The files themselves are not corrupt, because they'll open everywhere else, including Adobe Fireworks, but they will not open in photoshop. I checked to make sure the png plugin was present, and it is, and I tried to resave images in fireworks and in paint as png files and they still will not open in PS. I even tried creating a new png file in PS and once I close it photoshop will not open it again. So does anyone know how to fix this?
I read on other forums that sometimes anti-virus programs can interfere, does anyone know if Windows Defender does? Also, I read there's a posibility that the png plugin is corrupted, or it may not have installed correctly, but I cannot find anywhere to download the plugin to try and correct it if that's the case.
Never seen that. I usually have to set PS as the default for opening PNGs after a fresh install, but I've never seen PS unable to open PNGs.
If you need the plug-in, here's one that I KNOW works: http://tinyurl.com/n5ag65r
That's got the X86 and X64 PNG file format plug-ins in a zip.
Thanks Mark, that's exactly what I needed! I just replaced the old PNG plugin and it's working fine now. I really appreciate the help.
