Hey @arjit27singh this is a pretty good thread too that covers a bunch of the issues. If you’re on PC this is a workaround:
Thread: Don't work lottie extension AE - #63 by christie_shin
Workaround:
Install ZXP file manually.
- rename your .zxp file to .zip
- unzip the zip file
- drag that unzipped folder into the folder (on PC)
C:\Program Files (x86)\Common Files\Adobe\CEP\extensions\ - Create a registry entry “PlayerDebugMode” with String value 1 in
HKEY_CURRENT_USER/Software/Adobe/CSXS.5
(To create and modify registry entries you can search for the program “regedit” in the windows menu)
