Failed to Uncompress Cisco's OpenH264 codec

Just got started on Toon Boom’s free trial yesterday and made a short little test, but when I tried exporting it on the H.264/MPEG-4 (*.mp4) setting it tells me I need to install OpenH264.
However, when I press “yes” to downloading it, it tells me

“Failed to Uncompress Cisco’s OpenH264 codec.
The file may be corrupted or the utility to uncompress the file may be missing.”

Also, exporting on the Windows Media Video setting works just fine.

Unfortunately couldn’t find much on my issue. Is there something I can do to fix this?

I bought mine a couple months back and am having the same problem too (took a while on the project I was working on).

Same here.

I’m having this exact same issue, has there been any update?

I am having the same problem. Did you ever find a solution to this?

This appears to happen because the H264 codec is compressed in bzip format, but Windows doesn’t include a program that can uncompress bzip files. If you install a program that can handle bzip files and set it as the default, the automatic download and extraction should work.

Alternatively, you can manually perform these steps:

Toon Boom includes a program to uncompress the bzip file Cisco uses. I haven’t had issues install it, might be user account permissions.

If you are manually installing (WIN), this is a hidden folder C:\ProgramData\Toon Boom Animation\codecs
