If you are using CAD software, update the Engineering Link Software:
Use Windows Explorer to open the following directory on your network: \IsahSetup_[RELEASENO]_EngineeringLink\[UPDATEPACKNO]_[VERSIONNO]\.
Double-click the IsahEngLink_x86.msi file (if you are developing a 32-bit program). If you are using a 64-bit third party application or if you are developing your own 64-bit program, use IsahEngLink_x64.msi.
Follow the directions on your screen to carry out the installation process.
