Layout file was sent in watsapp but does not open

I had made a copy of sketchup layout on watsapp to work from home. now i am unable to access the file as it showing as zip fle

LayOut files are zip files but with the extension .layout. Edit the file name and change it to .layout and try opening it.

Please complete your profile with SketchUp version and graphics card model.

Thanks, but now it says Layout is older version and refuses to open., how do i update it?

What exactly is the message? Show a screenshot. What version of SketchUp and LayOut are you using? Again, complete your forum profile.

Use some other cloud or file transfer service that preserves file extensions (Google drive, OneDrive, TrimbleConnect, Dropbox, whatever)
Are you using a newer version of LayOut at work than at home? Or, at home, do you have more than one version of SketchUp/LayOut installed, and you are double-clicking on the file in a folder window? The file association might be locked to an older version. In that case open the newest LayOut first, and try opening the file from inside the application.

hi. your profile is a bit thin, I’m gonna suppose you have at least SU pro. what version do you have ? is it the old classic licence or the subscription ? are you still using an older mac sierra mac ?
what version is your correspondant using ?
(please add these infos to your profile so we don’t have to grill you for it later again :). click on your icon top right, then the silhouette, then profile)

you have two choices. they can re-save the file in an older layout version, or you can update your SU.
