The Prepar3D News has not been updated yet, I will post the Change-Log shortly

Prepar3D v4.3 has been released Prepar3D v4.3 (4.3.29.25520) Here is the official announcement Including the Change-Log https://www.prepar3d.com/latest-news/ Please see the link below for a step by step guide to update Prepar3D using the update component Installers You can also follow this link for a video tutorial on this process

Hello Mostly these texture Add on's will modify default files in the following folders, ShadersHLSL, Textures, Effects\Textures, Scenery\World\Texture, Scenery\Global\Texture, Sound, Weather Some of these Add On's do offer an uninstall process which will return these files to default again some don't. Willy does have the right Idea, To create a complete copy of your Prepar3D Install folder and then you can replace the texture folder and so on as required Failing that you could repair the components they fall into these categories 1) Client: ShadersHLSL 2) Content: Textures, Effects\Textures, Sound, Weather 3) Scenery: Scenery\World\Texture, Scenery\Global\Texture

Hello As the rest have suggested some light house keeping might help The link below will show you the locations of 3 files / foldres you could delete and let Prepar3D generate again, This will not effect your Add On's https://www.prepar3d.com/forum/viewtopic.php?t=127074#p170021

Hello Yes you can update from version v4.1 to v4.3 or even v4 to v4.3, Each component update is a full fat release which has all previous updates included

The Video Tutorial below was created by MarkDH on how to set up View Group for Prepar3D v4.2

If you have just reinstalled your Windows 7 Operating system But now it will not update please follow the steps in the link below. https://plugable.com/2016/06/08/windows-7-wont-update-what-to-do/

Hello Are you using the Add On Envshade ? If so this Add On will need to be update for Prepar3D v4.2

Hello Vic Yes we are saying the same thing. 1 License of Prepar3D Entitles you to Install 1 copy of Prepar3D on 1 machine. For example 1 License of Prepar3D v4 entitles you to Install 1 copy of Prepar3D v4 on 1 machine. 2 copy of Prepar3D v4 on the same machine will not function due to the register key's being tied to only one version. If a user has a License for Prepar3D v3 & v4 they can Install together as they will coexist (work) on the same machine no problem

Hello Bill You can only Install one version of Prepar3D v3 or v4 on the same machine, You can not Install 2 of the same versions of Prepar3D on one computer. But you can Install Prepar3D v3 & v4 on the same computer as they can coexist no problem together

Hello Don't worry about not being able to find the 2 files because you have already run the Delete generated files command Yes ? And this will remove all generated files ------------ If you were missing a Default Prepar3D yellow folder in the core location this would also give this Issue Can you see all 18 default yellow folders below in your core folder --------------------------------- Have you tried deleting the Prepar3D v4 Add-on's folders and the Prepoar3D v4 files folder in your Documents location ? -------------- You could Delete the complete Scenery folder above and then run a repair in the Windows Control Panel, Delete the Scenery folder, Then Right click on Prepar3D v4 Scenery and click Repair This will not effect any Add On's really. You will just need to reinstall Orbx Global base if you have it

Hello A small tip for anybody wondering (Like Me) Why your GTX Graphics card is over heating when Idle just surfing the Web. I have a 980ti and noticed with EVEGA Precision opened my Temps were heating to 75 C just browsing the web really. Initially I couldn't figure out why my card was getting so hot, It should Idle at 39 C with no fans running at all. It turns out I had "Preferred Maximum Performance" turned on in the NVidia Control Panel (Gaming Mode) This was set in Global Settings and not to an Individual Program, Meaning my card was always running on Maximum Power (Maximum heat) I turned this back to the default "Optimal Power" and restarted my computer and my Temps Immediately fell back to 39 C even with no fans running And that's was it, Just a small Tip but made me worry my Graphics card was on its way out Right click on your Desktop click into NVidia Control Panel > Manage 3D Settings > Global and scroll down to "Power Management Mode" Click "Optimal Power" and click Apply (Bottom right) When finished, Restart your computer If you have a Program you want to run on Maximun Power, Like Prepar3D, You can set this up in the Program Settings and not in Global Settings Note Ensure you also Adjust your fans for the extra heat , Or set up an Automatic Fan Curve In EVEGA Precision to kick in when the heat rises

Hello Mike Try these steps one by one......... 1) Regardless weather or not this will fix your Issue, Delete the Shaders folder and the Prepar3D.cfg file and let Prepar3D generate these again when launched next. 2) Do you have any FSDT Add On's, If so please See Here 3) Right click and Rename your 2 dll.xml files, the one in ProgramData and AppData\Roaming, Then launch Prepar3D, Shut it down and test ? Does this work ? 4) Right click and Rename your 2 exe.xml files, the one in ProgramData and AppData\Roaming. Then launch Prepar3D, Shut it down and test ? Does this work ? If Renaming any of these files resolved your Issue you can then look closer at your Utility Add On's You can just simply rename these files back again when you are finished

That worked Thank you. This is were i got confused last night 0 being set to #1 Perfect !

Hello Aaron There is an Option in the Windows Defender control panel called "Controlled folder access" Is this option turned on ? Its possible the latest Windows update has reset this option back to the default On position If so, Turn this Option Off, Then launch Prepar3D and test
