I just installed LTspice 24, I can use both old spice and new, they both work!

I still need to auto generate the models used by old LTspice (to build the symbols) to be able to use them in LTspice 24, is there a way that I can use the models in the new LTspice 24 with out regenerating please?

You are not very clear about what you have actually done.

Did you install LTspice 24 alongside your older existing version of LTspice (presuming V17.x), or did you effectively perform an upgrade over the top of your existing installation?

Or did you mean that old schematics created with your previous version still work with the new version?

You are also not clear which version 24 you have just installed. I presume you mean V24.1, since that is the latest one available on ADI's website? (There are significant changes between 24.0 and 24.1.) Now we're at 24.1.8 (at the time of writing), most of the initial issues arising have been addressed, but not all of them.

Whether you can use auto-generated symbols from your old version depends whether they still exist. Did you back up the old libraries? (BTW, you didn't auto-generate any models, it was the symbols you auto-generated from the models. Or do I completely misunderstand what you mean?) We can't know what you did unless you tell us. I would advise anyway, that you get out of the habit of using auto-generated symbols. There are several issues with them:

1. They are hard-coded with your local machine's absolute path, making sharing them problematic.
2. They contain no information about the function
3. They're ugly.
