So, that’s six years later and this problem still exists. I tried all solutions offered here and the only one that worked was David Wehle.

TWO spaces in the folder was the culprit.

Thank you and kudos for piercing this mystery.

Hello AfterEffecters,

I can’t believe this post started in 2012 and the problem still exist.

In my case, it started recently (never had that before) so go figure why it happened.

Anyway, Joseph Bourke’s suggestion to copy the .dll file from Quictime folder worked for me. Thank you, Sir.

Cheers all.

Yes, I got it, but ONLY after I saw your initial tip about track height. I wasn’t seeing them before.

Thanks again.

OMG, thank you. This was driving nuts. Still can’t figure out how to add a marker to a clip in the Timeline.

Thank you.
