Some pre checks before you download Prepar3D...........

1) Downloading Prepar3D (Download Manager)

For best results use a Download Manager to download Prepar3D (Important) They are free to use and will allow you the ability to resume a download if your Internet connection is disrupted.

After your download has completed you can now Confirm the MD5 checksum (hash value) on your download against the MD5 Checksum outlined in the Prepar3D downloads page to Insure you have a good download

I use the MD5 Checksum Utility tool to confirm the correct hash value on my downloads, This tool is free and easy to use.

Click the link provided, The download will automatically start, Then follow the steps below MD5 Checksum Utility

Step 1 (of 3)

Tick the Box for MD5. 1 Click Browse and navigate to your Zipped Prepar3D v4 folder

2 Double left click on the Zipped Prepar3D folder to add into the File box
