can I save as *.sl4

I have updated to Superlab 5.0 and am currently using programs created as .sl5.

I would like to be able to share them with a colleague who has Superlab 4.5. Is there a way to save my programs as .sl4?

Thanks

Unfortunately not. The file format in version 5 is upgraded. Version 5 can read v4 experiments, but not save them.

As a reminder, if you have an extra license, you can lease that SuperLab 5 license to your colleague.
