Changing Engine Directory
I want to ensure this issue is not confused with changing the location for where the content/marketplace items are downloaded.
I'm speaking about the actual 4.1, 4.2 directories that contain the engine itself - these are approximately 10GB each.
I have them both downloaded, however I want the launcher to pick them up/detect that I already have them downloaded instead of it saying "No Engine Installed".
Is there a way I can do this? Right now they're sitting in the following location: K:\Program Files\Unreal Engine\4.1 and 4.2. This is also where the launcher is located (K:\Program Files\Unreal Engine\Launcher).
There is a trick you can use to make the Launcher find the engines, and simply just verify the files locally. There will of course be some download if the engines already located there are not exactly the latest version, but hopefully you won't have that problem.
Firstly, navigate to
Then, navigate into the 4.1 and 4.2 folders and create an empty file named exactly "$movedMarker", no extension. e.g. you should have K:\Program Files\Unreal Engine\4.1\$movedMarker
You need to do that for both of the engines you put there.
When you hit the install button on the engine version you placed the $movedMarker in, the installation should show a "Verifying" instead of "Downloading" after it has finished initializing. At the end of the Verifying stage, if all seems in check then it'll be done, otherwise some data may be downloaded to 'fix' the installation files that were detected as incorrect.
Let me know how you get on!
If anyone have problems after reinstalling Windows, EpicLauncher ,Changing Engine Directoryor other situations through which You do not "have Installed" Engine and Epic Launcher don't recognising already installed Engine files then....
i'm just move directories, after this
IHello, I just reinstall win8. I had a previous installation of UE 4.12 and 4.15 The launcher dosn't see them and want to download again everything...
I look at the "C:\ProgramData\Epic\EpicGamesLauncher\Data\Manifests" folder but I have no "Manifests" folder in it, just a something.manifest file that I delete.
I add the empty "$movedMarker" in my UE_4.15 and UE_4.12 folders.
When I click on the install button, i can set the folder where I want the engine to be installed but if I choose one of these two (UE_4.15 or UE_4.12, witch contain the previous install and the empty file), The launcher give me the error "the folder have to be empty" and the install button stay grey and unclickable...
Is there a new way to do this ?
