  Opening Lumerical CAD/GUI with the following error:
```
../fdtd-solutions-app: error while loading shared libraries: libglut.so.3: cannot open shared object file:...
```
  The package, ‘freeglut’ which provides these libraries, need to be installed. For users without root access, manually download ‘freeglut’ from your Linux distribution’s website and then extract and copy this into the Lumerical installation folder.
  Install with root access:
  - RHEL/CentOS
```
sudo yum install freeglut
```
  - Ubuntu
```
sudo apt-get install freeglut3
```
  - SLES
```
sudo zypper install freeglut-devel
```
  Install without root access on RHEL/CentOS/SLES:
  Download the RPM package for your Linux distribution. Extract and copy the libraries into the Lumerical installation path on your machine.
```
wget http://mirror.cenos.org/centos/7/os/x86_64/Packages/freeglut-3.0.0-8.el7.x86_64.rpm 
rpm2cpio < freeglut-3.0.0-8.el7.x86_64.rpm | cpio -i -d 
cp /usr/lib64/* /installpath/lumerical//lib 
```
