Couldn't start Dropbox. This may be a temporary error. Please restart Dropbox.

Migrated data from my old Macbook Pro (Intel chip) to a new one (M2 chip).  Dropbox was the only program that did not migrate.  The dropbox name appears in Finder but with no files.  The dropbox icon on my menu bar is gone.  When I try to download the dropbox installer for the icon a message appears that the installer "Couldn't start Dropbox.  This may be a temporary error. Please restart Dropbox."  How do you fix this?

Hey @Daniel J.19, sorry to hear you're having issues with this.

Did you try quitting the app and relaunching it at all?  Could you check if this persists after rebooting your computer?

If it does, you may need to perform a clean, advanced reinstall.

In any case, please keep me posted!

Thanks for the message and suggestion.  I was able to do a reinstall.  The icon appeared and so did my dropbox files in Finder.  So far so good.
