Installation
Install Latest .NET SDK
You can get the typical SDK installation from Microsoft's official page
Latest
Install the latest SDK - it can compile patchers targeting any version, including older ones
Restart
It's usually a good idea to restart your computer after installing DotNet SDK to help things settle in.
Avoid SDK 10 if using Mo2
Mo2 is not interacting well with SDK 10 at the moment. Work is being done to help avoid the issue, but in the meantime, grab SDK 9.
Avoid install/uninstalling SDKs repeatedly
If after installing the .NET SDK as instructed above it doesn't work, try following this FAQ first
Runtime Is Not The SDK
.NET SDK-> Enables you to compile code (required for Synthesis to build patchers).NET Runtime-> Enables you to run the resulting exe patcher programs (or the Synthesis UI itself)
Be sure to install the SDK; The Runtime alone is not enough for Synthesis to compile patchers.
Optionally Install Runtimes
You can skip this step and wait to install a missing runtime when you see a patcher fail to run. This usually only happens when running an ancient patcher targeting ancient .NET versions.
The Runtime is version-specific. A patcher compiled for .NET 8 requires Runtime 8 installed to run. This is why an ancient patcher might require some older Runtime in order to be executed.
Multiple Runtimes Can Coexist
You can have multiple .NET Runtimes installed simultaneously without conflicts. Install whichever versions your patchers require.
Download Synthesis UI
To download Synthesis itself, go is the GitHub release section
On the latest release, download just the Synthesis.zip file. The other files are not needed.
Unzip the archive somewhere you like
Unzip All Files
Make sure you bring along ALL the files within the zip, not just Synthesis.exe
Dedicated Folder
The app will create a few files nearby itself, so it is good to put it within its own folder.
Run Synthesis
You're ready to run Synthesis!
