So starting today I noticed that simplify3D would not start. When selecting a file through Fusion 360 to print nothing happens. Trying to launc S3D throug desktop icon does not work either. Opening a S3d file does not work either.

I ununistalled both my original version of S3d as well as the lattest updated version. Restarted windows 10 and did a fresh install of the latest download. No dice.

Restarted desktop, no dice!

Restored desktop to earlier date, restarted computer no dice!

Simplify3D will not luanch.

Any insight would be appreciated.

Thank you,

~BG~

Can you try the following:

Open Windows Explorer and navigate to the following directory:

C:/Users/%USERNAME%/AppData/Local/Simplify3D/S3D-Software

You may need to enable hidden folders to access this directory. Once there, please try deleting the file called "savedState.factory". Then, open Simplify3D again.

This worked for me.

SavedState was a directory not a file.
And I also deleted every other file in the S3D-software directory.

Hi Barvogolf,

I'm experiencing the same issue and also made a post about it.
I usually fix the application startup issue deleting this exact key "HKEY_CURRENT_USER\Software\Simplify3D\S3D-Software\MainWindow" which looks to contain some file hostory information of some sort.
This way your profiles wil be untouched and you dont have to waste time to reconfigure the entire program, which i did like a couple of times...

Hope this helps for u and the devs will fix this issue soon.

there is a bug in windows 10 open gl on multiscreen setups ... I'm not able to figure out where / how it is happening but s3d is not only app affected (same issue with slic3r, prusa slicer, netfabb..) and solution for s3d is to delete all the registry keys under "HKEY_CURRENT_USER\Software\Simplify3D\S3D-Software\" that are named "geometry". This resets the location where s3d tries to open window at and everything works until you move any of the s3d window to your "non primary screen" and close it, next time you try to open that it will not work.

no clue how to solve this on system level, so far everyone I know having this problem is windows10 and nvidia.
