If you can't locate the uninstaller, go to Settings -> Apps & Features and locate Syscoin Core and click on Uninstall.
The uninstallation process will remove previous software, not your wallet data.
After Syscoin 4.0.x is uninstalled, please proceed to installing 4.1.2 normally.
On Linux and MacOS, you can choose to use the pre-built binary (.dmg for MacOS) or build from source code:
If you ran 4.0.3 before, please do the following first before checking out the latest code:
cd ~/syscoin git checkout v4.0.3 sudo make uninstall make clean
This uninstall the 4.0.3 binaries from
/usr/local/bin and then clean up the repo
Proceed as usual after
git checkout v4.1.2 ./autogen.sh ./configure make sudo make install
Download the binary
