Trying to save but "Read Only Mode" error comes up


I am a student running Rhino 7. I have been working on a file for a few weeks now and when I attempt to Save a error occurs saying “File opened in read-only mode. You must use SaveAs to save changes”. Is there a way to prevent that from happening? I have no intentionally turned on Read-Only mode, and I do not want multiple copies of the same file. Any advice would be appreciated

It may be that Rhino has crashed at some point. You’ll probably find a file ending with the extension .rhl. If that is the case remove that .rhl file. You should be able to open the file again in read-write mode.

Hey @nathanletwory, I am getting this bug all the time since ~2 weeks, which is super annoying. The files are definitely not read only and there is no .rhl present.

I would be very happy if McNeel could tackle this, before it never occured to me in this way.

Did you install Hops? If you did, please run PackageManager and make sure you have the most recent version.

Oh yeah this might be the culprit. Indeed the version was a little outdated. After the update I had no such issues yesterday. Fingers crossed that this was it :wink:

Thank you for your immediate help Steve! Greatly appreciated :slight_smile:
