NS_E_WMP_PNG_UNSUPPORTED_INTERLACE (0XC00D102C) fix
This error pops up in Windows Media Player when a PNG has interlacing enabled. The fix is simple — re-save the image without interlacing.
You're trying to open a PNG in Windows Media Player (WMP) — maybe you dragged it into the library or double-clicked it — and you get that error: NS_E_WMP_PNG_UNSUPPORTED_INTERLACE (0XC00D102C). The player says the interlace method isn't supported. This usually happens when the PNG was saved with interlacing enabled, which is common in images exported from Photoshop, GIMP, or some online converters. WMP just can't handle the Adam7 interlacing scheme that older PNGs often use.
What causes this
PNG files can be stored two ways: progressive (interlaced) or non-progressive. Interlacing lets the image load in passes — you see a blurry preview that sharpens up. It's great for web browsing on slow connections. But Windows Media Player's PNG decoder is bare-bones. It only reads non-interlaced PNGs. The culprit here is almost always the Adam7 interlacing method — the only interlacing scheme PNG supports. WMP hits that flag and bails out with 0XC00D102C.
Don't bother checking codec packs or reinstalling WMP. That won't fix it. The image itself is the problem.
How to fix it
You need to re-save the PNG without interlacing. You can do this with any image editor — even Microsoft Paint works. Here's the quickest way using Paint (comes with every Windows).
- Open the PNG in Paint
Right-click the file, choose Open with > Paint. - Re-save without interlacing
Click File > Save as > PNG picture. Overwrite the original file or save a copy. - Try opening it in WMP again
Double-click the new file. Should work now.
If you have GIMP or Photoshop, the option is in the export dialog — uncheck Interlacing or Save as interlaced. In GIMP, when you export as PNG, it's a checkbox labeled Interlacing (Adam7). Turn it off.
What if you have a lot of files?
Got a folder full of interlaced PNGs? Use a batch converter. XnConvert is free and handles it well. Set the output format to PNG, and under Options, uncheck Interlaced. Run it on the whole folder.
Still failing? Check these
- Corrupted file — If the PNG is damaged, re-save might not help. Try opening it in a browser (Chrome, Edge). If that also fails, the file's trashed. Re-download it.
- Wrong file extension — Some people rename JPEGs to .png. Check the actual format by opening in Notepad — a real PNG starts with
‰PNG. If it doesn't, change extension back or re-save properly. - WMP version — Old versions of WMP (like in Windows 7) have this limitation. Newer ones (Windows 10/11) still have it. No workaround other than fixing the file. Use a different media player — VLC plays interlaced PNGs fine.
- Third-party codecs — Installing LAV Filters or K-Lite Codec Pack can let WMP decode interlaced PNGs. But it's overkill for one image. Only do this if you hit the error often and don't want to batch-fix files.
Bottom line: WMP is not a real image viewer. It's a media player that barely handles PNGs. If you keep seeing this error, switch to IrfanView or FastStone Image Viewer for photos. They handle interlaced PNGs without complaining.
