Preview and publish shows error after a while

here is the source code of the problem (-> Articulate.Design.dll)

private static bool a(string A_0, IAsset A_1)
{
  if (!string.IsNullOrEmpty(A_1.WorkingFilename) 
    && File.Exists(A_1.WorkingFilename))
  {
    File.Copy(A_1.WorkingFilename, A_0, overwrite: true);
    return true;
  }
  return A_1.SaveAssetToFile(A_0);
}

storyline want's to overwrite an existing image and this is not possible at this moment*

*overwriting/deleting files is not easy in windows

everone who has this problem should open a support case

perhaps then they will fix the not error-tolerant use of System.IO.File.Copy in overwrite mode

Thank you, Jürgen - I'll open a case soon. 

Adding a preview error here for reference. I was randomly previewing slides when it popped up.

Hi Robert,

Thanks for letting us know you've opened a support case. One of our talented Support Engineers will be in touch shortly via email!

Have a great start to your week!

I think it's solved as I am not getting the errors for a while now. 

But I am not sure what was the problem or how it got solved. I tried all the steps below (mostly suggested by John Carlo from the support team) -  one or ore must have helped somehow. 

1) Close the Articulate 360 desktop app by right-clicking the Articulate icon in your computer's system tray (by the clock) and choosing "Quit."

2) Go to your Control Panel and uninstall all Articulate 360 apps, including the Articulate 360 desktop app, Peek 360, Replay 360, Storyline 360, and Studio 360.

3) Download and extract this zip file on your computer: http://articulate-360-kb.s3.amazonaws.com/360cleanup.zip

4) Right-click the 360cleanup.bat file and choose "Run as administrator." The script should only take a few seconds to remove all the Articulate files and registry keys from your computer.

5) Reboot your computer.

6) Download the latest Articulate 360 desktop app here: https://360.articulate.com/downloads

7) Right-click the articulate-360.exe file and choose "Run as administrator."

8) Launch the Articulate 360 desktop app and click "Install" beside each authoring app you want to install.

9) Reboot your computer and test your Articulate apps.

---------------------

1. Right-click the Storyline icon on your desktop and click Properties. If you don't have the icon on your desktop, search for it in the Start Menu instead and right-click. Choose Open File location. From there, right-click the Storyline icon and choose Properties.

2. Go to the "Compatibility Tab" and tick "Run in Compatibility" mode for Windows 8.

3. Save the changes and test Storyline 360.

If the issue persists, consider creating a new user profile on your machine in case it's an issue with the current user's settings.

---------------------

I also disabled my secondary graphics card in device manager. See attach. 

---------------------

Articulate also released a few updates in the meantime maybe that helped as well. 

Wonderful news! Glad to hear you're no longer having this issue.

Thanks so much for sharing in the thread, Robert! I'm sure this will be helpful for others that come across this post!
