How to revert to previous release

Certainly. There are a number of reasons this could be happening, let us know if the 8.19 resolves it.

Thanks! Moving to 8.19 worked

Hi Japhy, I am encountering the same problem with the latest Rhino 8 update, Rhino won’t start because of plug-ins errors, can you please be so kind to send me the previous release version of Rhino 8 Window English? Thank you

Hi Nguyen Khoi Chu,

The current release is 8.22, sending you 8.21. If that doesn’t resolve your issue we should start troubleshooting your plugins.

Hello,

Updated Rhino 8 to 8.22 and getting this error. Can you pls help in resolving or giving earlier stable release.

hi @kamal.dahiya.26 I recommend trying a Rhino repair first. Click Modify

Then in the next dialog choose Repair

Hello, tried.
Even tried the classic uninstall and reinstall.

A manual deinstall might help resolve this.

Did not work, can you pls send the 8.19, cause that version was working fine before i updated.

Pm sent

Hi all. got a similar issue here. Would like to roll back the update since ladybug tools does not work with the latest release. Would be grateful for your help :folded_hands: (Solved. My bad. it was such a clash between pollination and LB manual install)

Hi, having an issue with grasshopper gold after the most recent update on Rhino 8, could anyone send me the download link for the previous version?

Hi Brenda,

What is the issue?

How long has it been since you updated? Any particular version you would like to try? I’m assuming this is windows Rhino.

Hi,

This is the error code that I get when trying to use grasshopper gold, I updated rhino yesterday to Version 8 SR24 the version before this would be ideal! Yes this on windows.

Hi Brenda, Those are default components. Try a repair install first. Go to Add/Remove Programs and Modify the Install / Repair.

I’ll send you 8.23

Hi Japhy, thanks so much for this recommendation - I was able to repair with no problem.
