  • Download the new full installer and update Materials Studio. You can obtain the full installer from the Accelrys electronic software distribution (ESD) site.
  • Use the Windows Update installer to update your 32-bit and 64-bit Windows installations
  • Use the Linux Update to update your Linux installations

For more details on the changes contained in this update, see Materials Studio 5.5 Updates.

Installation of the Windows Patch

On Windows: Download MS55Update1.exe (HTTP|FTP) and execute the following commands:

1. Ensure that all Materials Studio client applications are closed and that no jobs are running by either;

  • restart your computer
  • or use the Remote Gateway web interface to stop any running jobs and close any remaining instances of MatStudio.exe and DSMgr.exe processes using Windows Task Manager. If the Server Console is open you must close this before stopping the DSMgr.exe process.

Note: If any Materials Studio process is running when you start the update the installation will not complete successfully.

2. Run MS551Patch_Windows.exe to start the update.

This will update your Materials Studio installation to version 5.5.1.

For 32-bit installations this will run a single patch installation for the 32-bit components of Materials Studio
For 64-bit installations this will run two patch installations in turn, for the 32-bit and then the 64-bit components of Materials Studio.

Tip: You must allow both of these updates to complete before restarting Materials Studio on 64-bit installations.

Installation of the Linux HotFix

On Linux: Download MS55Update1.tar.gz (HTTP|FTP) and execute the following commands:

1. Decompress and untar the archive

tar -xzf MS55Update1.tar.gz.tar.gz

This operation creates two subdirectories with specific Linux libraries


These libraries should be used on Linux ia32 (Linux) and x86_64 (Linux_x86_64) hardware respectively. They should replace the libraries provided with the 5.5 Materials Studio release.

2. From the command line, locate the installation directory for Materials Studio:


where $MS_INSTALL_ROOT is the location of the Materials Studio installation on the Linux server.

3. Create backup copies of the library in the installation directory


4. Replace in the installation directory with the library from the patch archive overwriting the original file:

cp MS551Patch_Linux/Linux/ $MS_INSTALL_ROOT/lib


cp MS551Patch_Linux/Linux_x86_64/ $MS_INSTALL_ROOT/lib

Note: Restarting the gateway is not necessary.
