Problem with Open/File in SketchUp 2015

[JBJDesigns]

Hello! Ever since I upgrade to Windows 8.1 Pro, 64-bit, I’ve been experiencing a problem opening and re-opening SketchUp files. When I initially open SketchUp and open a current file, there’s no issue. It’s after I save and close the file, then try to open it again. I get the following error message:

The file
‘C:\Users[name]\Documents\GoogleSketchup.…[file name]’ is currently locked by another user. Do you wish to open this file as Read-Only?

I’ve tried running SketchUp as “administrator” with no change to the problem. So far, the only way I’m able to open the file again is to close SketchUp, Restart the comptuer, and return to SketchUp and the file I’m working on. By the way, this happens to ALL the files I’m working on. ALSO, I did go through my folders and made sure I had full control over the Document/SketchUp file folder.

Thanks for helping me out.

Specifically, close SketchUp, then turn off these 3 features in explorer, (as explained in the post below,) then rename the “ThumbsUp.DLL” file to something else “ThumbsOLD.DLL”, etc. Reboot the computer.

Why does SU think the file is open?

And I found another post that says file locking occurs on Win7 also with the Details pane and Popup file tooltips active. (It is in the Microsoft Excel Support Team blog. The item was posted 3 years ago.) ALL 3 need to be turned OFF: Apparently as you are double-clicking to open the file, Explorer is trying to read information about the file, to display in the Details, or popup tooltips. [quote]III. Turn off the Preview Pane, Details Pane and pop ups that show information about file and deskt…

Hello Dan! Thank you for the guidance. I’m using Windows 8.1 so the steps
to “turn off” certain features is a bit different. I was able to take
control of the SketchUp folder and files, so the issue has been resolved.
Thank you very much!!! Jo Ann

Hi. Solved this on my machine by turning off the preview pane then double-clicking the file as normal. I then turn the preview pane on and off as needed. Saves tinkering about with permanent setting changes.

I then turn the preview pane on and off as needed.

ALT-P does the trick.

Read this article to see where SketchUp puts its auto save files. Hopefully you’ll find one that is in good condition: Setting Software and File Preferences | SketchUp Help
