I am reinstalling P3Dv4.2 and have encountered a very frustrating problem.  Wondering if anyone has encountered similar problems.  When unzipping the file or upon installation, winzip reports checksum and or/hash total errors and aborts the unzip or install process.  I have tried downloading the files individually, I have used different pc's for the download, I have used different browsers for connecting to the P3D download site and initiating the download eliminating every combination of variables I can think of.  When installing from the individually downloaded files, the installation fails - I tried both installing as an administrator and a regular double click install.  All with the same result.  I am using a fresh Winzip v22 and I have tried the native Microsoft Win 10 unzipper both with the same result.

In the past have been a user Starting with P3D v1.x and never had any sort of issue.

  Any thoughts would be appreciated

Sound like corrupted download files is your AV interfering.

Do the checksums match? I use HashTab to check and 7-Zip to unpack. Both are free for personal use by the way.
