I want to download older version (1.9.10) of Omniverse launcher, the reason is my team is still using External App Template, not migrated to Kit App Template (github) yet. I see that its automatically downloading latest version of Omniverse launcher, 1.9.13 from Develop on NVIDIA Omniverse Platform | NVIDIA Developer.
Hello there and thank you for your inquiry. It is not possible to download older, previous versions of launcher. The download link only allows downloading the latest version.
However, this is not an issue. The latest version of launcher still offers the same exact versions of all the software that you need. The version of launcher is not directly tied to the version of the software.
Therefore, please go ahead and download the latest version of launcher as normal, and then download whatever version of kit or USD composer you wish to use.
