Integrity Check is  enforced with the following files. Got to your start menu -> Eagle Dynamics -> DCS World or DCS World Openbeta and click on “DCS REPAIR” – it will automatically replace the deleted files. Click Here

If you choose to perform a complete re-install of DCS – make sure to delete remaining folders. Mods WILL LEAVE ORPHAN FILES that will fail Integrity Check subsequently!

(Delete these files before performing the repair)
