          so what i did to get it to work was start downloading the game then pause it. move the original RedDeadRedemption2 folder into the folder that contains the new download, not the new folder but in the folder before it so they merge then i went back into epic games and then resumed download. the epic games launcher started verifying it as if it already downloaded

WTF is wrong here? I can't be downloading the same 40 GB games over and over ad infinitum I am beginning to really hate EPIC....


            This 100% worked. Thanks g, now I can play Shenmue 3 on the go with my surface

              You don't need to reinstall Epic Games Launcher
              It worked for me this Instructions for Recognising already installed game in Epic Games Launcher:


              - Rename the game file to another thing such as "_GameFolder"
              - Open epic games launcher and start to download your game, when its 1~ mb cancel it
              - Close epic games launcher(not from taskbar)
              - Press win + r and type "temp" , then delete all files
              do it again by typing "%temp%" "prefetch" and "recent" , too
              - Now rename "_GameFolder" to without "_" , like this "GameFolder" (You must rename folder with same name made by Epic Games)
              - Open epic games launcher from taskbar (it is already running in background)
              - Click continue to download

              Now it is going to verify game automatically.

                I recently updated my OS to Windows 10 as a clean install. In the new OS, I installed Epic Games Launcher to it's default directory on drive C, same location as it existed on Windows 7.

                When I logged in, my Library had all of the games greyed out as though they were not installed. But my previously installed games did still exist on drive D. This probably has to do with the new launcher install not having the manifest data that the old Windows 7 install had created over time.

                If you try to install (re-install) a game you know has already been installed, the EG Launcher will not let you install (or re-install) to a directory that already exists. It says "Directory must be empty.", when you try to install to the original game directory.

                1. Go to your Epic Games directory with Windows Explorer. It's usually C:\Program Files\Epic Games, unless you originally installed to a different location. Mine was on drive D.
                2. Find the game folder you want to reinstall (get working) and rename it. I just put an underscore in front of the original name. ex. _ShadowComplexRemastered
                3. Start the install from the launcher. It will ask you to "Choose install location". Select the base Epic Games folder where your game files are already installed. ex. C:\Program Files\Epic Games. It will then show that path and add the game folder to the end. ex. C:\Program Files\Epic Games\ShadowComplexRemastered. Click Install.
                4. Let the Launcher download a couple MB's and "Cancel" the install, but leave open the launcher. Now you have a nearly empty brand new game folder in your Epic Games folder.
                5. Go back to Windows Explorer and rename the brand new folder to anything else. Then, go to the original folder you renamed and name it back to it's original name. You can delete the newer empty folder.
                6. Go to Launcher and click "Resume". The launcher will immediately Verify all files and you'll be ready to play.

                Epic Games devs, it would be super helpful for users to have a "Games Install Location" on the launcher Settings page, so the launcher can automatically recognize files in a pre-existing directory and immediately verify them.
                Thank you!!!!! This verification method works EXACTLY as he said with all the little caveats done in order (not pausing, but canceling, then resuming after renaming and deleting). Thank you!!!!

                Epic Games really needs to do a UbiSoft/Uplay, Origin, or Steam style easy way of game verification so that hard drive, OS, or any other upgrades do not mandate a re-download of games for those who are not successful with this method. The other portals have done it, so it should not be a big deal for Epic Games to have it done; would make their platform more profitable. I had to deal with these archaic ways of re-downloading until some benevolent sharp users posted solutions herein for the rest of us poor souls.

                Running Windows 7 on AsRock Ryzen 7 system (yes, late-gen AMD chipset motherboards actually work with Windows 7 if you swap pre-installed Windows 7 hard drive over to new AMD system, and use PCIe USB riser cards to get around lack of USB support with anything but a late-gen MSI Board [MSI still supports Windows 7 for their AMD chipsets]).

                    Thank you! This works exactly the way you said. The only thing I did differently was to only delete the files showing Epic Games and my games name, instead of the entire temp/prefetch/recent files. No reason really not to delete them all, I just was being a bit cautious, and it worked great!

                          epic games needs to sort their **** out, honestly. Its so frustrating! For a platform with such a great game, surely they can invest in a better version of the launcher that doesn't do this all the time! Especially the issues people have with multi user computers!

                            I have the solution for avoiding redownloading all your Epic games.
                            - Delete only the previous launcher folder: C:\Program Files (x86)\Epic Games
                            - Clear all temporary files:
                            C:\Users\(ACCOUNT)\AppData\Local\Temp
                            C:\Windows\Prefetch
                            C:\Windows\Temp
                            - Install the latest Launcher.

                            For those with 2 OSes using Launcher:
                            - Have each OS contain its own folder of the launcher (NEITHER CAN SHARE IT APPARENTLY AS YOU'RE HAVING A PROBLEM).
                            Having ~500-1000MB wasted is less than ~tens or hundreds of gigs, redownloading each time.
                            - Follow above steps to remove older Launcher if problems arise.
                            - Have both installations of Launcher link to the same games folder: C:\Program Files\Epic Games > NOT C:\Program Files (x86)\Epic Games
                            * Or install each OS on a seperate drive.


                            This did not work at all!!!

                              I've found another workaround to the previously-installed games issue - launch your Epic games from Steam.

                              1) In Steam, go to "Games" in the header menu, then select "Add a Non-Steam Game to My Library."
                              2) Your Epic games may show up in the list that follows (depending on where your game folder is). Otherwise, hit "Browse" and navigate to your Epic Games folder.
                              3) Select a specific game folder, find the .exe file and double-click. You'll end up back at the previous screen, with the game selected.
                              4) You can keep navigating to your other game folders and selecting the .exe files. When you're done, hit "Add Selected Programs." You games will show up in your Steam Library and will open when you click on them (note: you'll need to have the Epic Games app running).

                              I discovered this because I'd already added all my Epic games to Steam before my clean install of W10. If you're already using Steam as your main PC game launcher, this workaround may be for you.

                                Also confirming that this works (thanks, Ruzz)

                                I did a bit of harddisk swapping. The old drive was G: and the new was S:
                                But this did the trick
