===RHEL/CentOS 8===
We have successfully installed Wine 5 on RHEL 8 using the following commands: 

(These build Wine from source, hence the installation takes considerably longer.)
<code>
sudo -i
dnf clean all
dnf update
dnf groupinstall 'Development Tools'
dnf install libX11-devel freetype-devel zlib-devel libxcb-devel libxslt-devel libgcrypt-devel libxml2-devel gnutls-devel libpng-devel libjpeg-turbo-devel libtiff-devel gstreamer1-devel dbus-devel fontconfig-devel
cd /opt
wget https://dl.winehq.org/wine/source/5.0/wine-5.0.tar.xz
tar -Jxf wine-5.0.tar.xz
cd wine-5.0
##For 32-Bit Systems:
./configure
##For 64-Bit Systems:
./configure  --enable-win64
make
make install
</code>

===Configuring Wine===
After installing Wine, if you encounter errors about Mono, a useful trick is to delete the folder **.Wine**  and force Wine to download and install Gecko and Mono automatically. Normally, Wine will suggest installing these the first time it is used. Furthermore, opening the ''wine uninstaller'' and removing interfering applications might solve some problems. In the end, we are able to use Wine without installing Winetricks or dotnet manually. If you are working on a remote machine, you might need to enable X11 forwarding to see the windows created during the Wine configuration. This is done by connecting via **ssh -X** and modifying the **ssh.config** file under **etc/ssh** accordingly. On RHEL/CentOS 8 some dependencies might need to be installed by the following command:
<code>
# dnf install  xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps -y
