I have a problem I am using Lightroom 3.5 and started to have a problem with the slideshow component.
I get the following error:
Log (3)
Cannot create the encoder instance, h264OutVideoNew failed.
error: h264OutVideoChkSettings - no library function available
error: No encoder library could be found!

Thanks for any help you can provide!

Try this:
In Finder, go to your Applications folder.
Select Lightroom 3.5 and do Command-I to open information
Look for "Open in 32-bit mode" under the General area.

Is it checked? if so, try unchecking it, then start Lightroom and see if the slideshow export works.
