Direct Link To This Post Topic: GEP3D CONTENT AND P3Dv4 UPDATE - RELEASED
    Posted: July-22-2017 at 3:43pm


Ground Environment Prepar3D World Edition

Update to v1.10

Many images are provided below. More can be found here:  (click the +19 box)

Thank you for your support!


This update provides a content update as well as Prepar3Dv4 compatibility. We have added textures as well as reworked hundreds of texture sets. GEP3D updates are free and will always remain that way.

Update includes changes to Europe and many other locations. The landclass in use will define the texture accuracy in the simulator. We recommend Ultimate Terrain X products for that purpose.

Clicking 'Check for Updates" in the GEP3D interface will lead back to this announcement. Due to the amount of data that was changed in this update there is no 'update patch'. Updating the product is a simple process of download, uninstall-reinstall, then enable in Prepar3D. There will be an additional texture update later this summer.

I am providing detailed information here in order to assist anyone who may need specific instructions.

The update process is very easy to do...

For those who use HASH CHECK to verify files are not corrupt you can download the 2 hash check files here: 

This is a very large download. You may wish to consider the use of a download manager. If download speeds are slow it is probably because the links are experiencing heavy traffic however if you have issues getting the files such as broken links please post in the forums and let us know.
1. Please make sure your AV/Malware scanners are disabled so they will not interfere with download of the product.
2. Click each link and once the files are downloaded place the 2 files in a single folder on the desktop.

3. You are now ready for the unwrap/install process. If you have GEP3D v1.0 currently installed it must be properly removed before proceeding.

If this is a first time purchase and/or use, you may skip the next section and go directly to: UNWRAP AND INSTALL GEP3D v1.10



1. Open the GEP3D interface by right click of the GEP3D shortcut, select: Run As Administrator.

2. In the GEP3D interface, select the green bullet next to 'Ground Environment Prepar3D World Edition' and then click the DISABLE button.

This will restore your backup and automatically reset the UTX features you may have enabled. Once complete, close the interface.

3. In Windows, browse to: Control Panel > Programs and Features. Scroll down to 'Ground Environment Prepar3D World Edition' and select to uninstall. Allow the process to complete.


NOTE: Your backup will remain on the system and will not uninstall with the product. You have three choices to work with:

a. Manually delete the backup directory GEP3D_BACKUP and start clean.

b. Leave the GEP3D_BACKUP directory alone, browse the updated GEP3D 1.10 interface to the root directory where GEP3D_BACKUP is located and continue to use it.

c. Keep the original GEP3D_BACKUP and let the interface create a new GEP3D_BACKUP directory elsewhere on the system.





GEP3D does not install any files into Prepar3D until the user runs the interface and instructs the interface to enable the files in Prepar3D. You can install the GEP3D World database on your system to any location you wish. The product does not require installation to the Prepar3D install directory where it takes up space for no reason.

Should you wish to change the default install path during the installation process you may do so. There is no install path requirement. You can elect to use the default path, or, browse the installer to the location of your choice.....
1. Please make sure your AV/Malware scanners are disabled so they will not interfere with install of the product.
2. With both files in a single folder on the desktop, right click the file: F1GEXP3D.exe and select "Run As Administrator". If you are reinstalling simply use the "Click Here to Reinstall" button and use your key/password to decompress.

If this is a first time purchase, follow the directions in the wrapper to purchase the product and begin the decompression process. 

3. A license will be generated specific to your hardware. This license is required in order to run the actual installer as well as the product interface. Do not remove the C:\Flight One Software directory however you can move the decompressed installer files from that folder after installation is complete. Once finished close the wrapper/installer.
NOTE: If you elect to not automatically run the installer after the wrapper finishes decompressing the product, make sure when you do run the installer to right click GEPrepar3D.exe and select "Run As Administrator"

6. It can be possible very aggressive AV/Malware scanners may read the GEP3D interface exe a false positive when the GEP3D interface is opened. To completely avoid this possibility enter the settings for the scanners and select to EXCLUDE the directory shown below:
 C:\Users\<YOUR USER NAME>\AppData\Roaming\Flight1 Aviation Technologies\GEP3D  <---- this directory and all files in it


Start the GEP3D interface by right click of the GEP3D shortcut the installer placed on the desktop, select: Run As Administrator. Follow the prompts for first run of the product. With Prepar3D v3 (and above) the interface will request a browse the Prepar3D.exe install folder the first time it is run.

Browse the interface to your Prepar3D install folder. Once located the interface will begin to perform its automated backup process. Select the backup location and allow the entire process to complete. If you have selected to use a original backup location, NO FILES will be overwritten, only added too the backup.

Enable GEP3D in Prepar3D by clicking the bullet next to the line 'Ground Environment Prepar3D World Edition'  and then click the ENABLE button. Repeat that process to enable any UTX region products that are 'LOCATED' by the interface after GEP3D World Edition is enabled.

That's it! Ground Environment Prepar3D is ready in the simulator. Remember there is no need to have the interface running after the ENABLE process is complete. The files will remain until you disable GEP3D which restores the backup to the sim.

The GEP3D Manual (HELP BUTTON) will define most issues and solutions to them should any issues arise or you are welcome to use this forum to request support.




There are special instructions for those who are currently using 2 versions of Prepar3D (v2, v3 and v4) and wish to run GEP3D in both at the same time. Please refer to this post:

Images of some of the changes..   I will add more  Big smile
This next image is a unrealistic view where no haze or weather is present and demonstrates how that even at 40K+ and with tube flying our texture design does not generate hard repeating patterns in the distance. 
.... more images to come  Smile
