{% hint style="warning" %}
The Manager requires the [**GameLauncherCore.dll**](#user-content-fn-1)[^1] to work. Let's create the dll.
1. In Visual Studio, right click on the **GameLauncherCore** project -> **Build**
2. Again, right click on the **GameLauncherCore** project -> **Open Folder in File Explorer** and Navigate to ***.../Build/Release*** folder
3. **Copy** the **GameLauncherCore.dll** in the same folder as the **PatchManager.exe**
**It must look like this**\
\
After this, **Open** the **PatchManager.exe**
{% endhint %}
## **This new manager allows you to create patches without Unity**
## Patch functions
### **Patch Type**
Create patches/updates by type
* **Patch: 1.0.x** (Example: 1.0.0 to 1.0.1)
* **Minor: 1.x.0** (Example: 1.0.0 to 1.1.0)
* **Major: x.0.0** (Example: 1.0.0 to 2.0.0)
This allows you to create a new type of updates.
### **Binary Diff Quality**
Select the quality of the binary diff comparison between patches/files.
**Selecting a Lower Level of Binary Diff Quality will cause this:**
* The patch will be created faster (Good for bigger projects)
* The final patch file-size will be larger
### **Ignore Paths**
Exclude files or folders from being considered for the Binary Diff Comparison in the patch.
### **Select which patch do you require**
Now you can select which type of patch do you want to create.
{% hint style="info" %}
**Maybe you don't want to create an installer patch of your 50 GB game on every patch right?** This will take a great amount of time. So let only one version of the installer patch for your users like the 1.0.0 and let the launcher update it to the last version.
{% endhint %}
Create an installer patch only on Minor or Major updates
You can select if you want to create:
* **RepairPatch** (This patch is applied when some file is corrupted or missing)
* **IncrementalPatch** (This patch is applied when the user has the last version and only needs the newer changes)
* **InstallerPatch** (This patch is applied when the user doesn't have any file of the app/game)
**Create patches for every old version to the new one**
This option will create a new patch from every old patch, using this, the user will download only 1 patch instead of download one after other.
We recommend to use this feature when you create a Minor or Major update.
1.0.0 -> 1.1.0
1.0.1 -> 1.1.0
1.0.2 -> 1.1.0
1.0.3 -> 1.1.0
**CLI Support**
