"P3D has detected non sequential layer within the scenery library list."

 

What version of P3D please? Do you have Lorby’s Addon Organizer?

P3DV5.  I don't have Lorbys organiser but I do have Fortek.

Had a lot of problems setting up Orbx, but all good now.

Sorry Ray,

The Orbx thing is sorted but still getting the  "P3D has detected non sequential layer within the scenery library list."

The file layout is quite different on my PC, so will have to look harder at it.

As for Orbx it has died totally, so I will try to uninstall and re-install.  Before it died I kept getting errors and it kept saying I did not own any software.

Now Simconnect has stopped working and the dash 8 has also died.  I am thinking that I have HDD problems. I have used Fortekt but hopeless.

The new version of Windows unrecognisable, the interface is unrecognisable.

Sorry to burdon you with this but I am having trouble working out the right support centre for the right issues.

I might just put a new HDD in and start again, hopefully without Win11.

Kevin, don't do anything drastic at this point. To check the integrity of your HDD do the following:-

Open Command Prompt as Administrator and run chkdsk C: /f /r /x  to locate bad sectors and repair file system errors.

Please note you need to respond Y and reboot your PC. When it starts the check begins.

Report the results. In all honesty if the HDD is failing get a SSD but if possible do a backup of your entire HDD using free software like Aomei.

Another thing you could do is right-click the Windows Start button, select Event Viewer - select Event Viewer (Local) and report how many Critical and Error entries in the last hour.

When you've completed the check do this to find the results:-

How to Find the CHKDSK Log:

Method 1: Event Viewer (Recommended)

Right-click Application and select Filter Current Log....

In the "Event sources" dropdown, check Chkdsk and Wininit.

Locate the most recent entry with Wininit as the source to view the log.

Copy and paste the results from the entry,

OK, I've outsmarted myself, shut down Onedrive again, turns out it was controlling everything.  everything I try to do gets "Access denied, you do not have permission to access Onedrive."

I am looking at going to Apple Mac as I am sick of Microsoft.  Well I've vented, but can't see that working.

The other alternative install a new HDD.  All my data files are on 😧 so it is only the sim that will need to be installed.  I guess this is where I come accross some 'Maximum  number of installs exceeded."

The current drive is SSD.

Problem,  I will have to download the latest Win 11 (with Onedrive attached) no doubt.

I figure if I can kill Onedrive immediately after install I should be able to sort things out my way.

I appreciate your support.
