Before You Proceed
Gather all the necessary information that follows about the installation:
• Check the following documents for the latest installation settings:
◦ The Hardware Notes for platform support, system requirements, and supported graphics card details at http://www.ptc.com/WCMS/files/160242/en/PTC_Creo_Future_Platform_Support_Summary.pdf
◦ The READ THIS FIRST document of your product for any changes to your computer settings
◦ The FlexNet License Server Hardware Notes for license server installation requirements at www.ptc.com/WCMS/files/121640/en/FlexNet_Licensing.pdf
• Make note of your product code that arrives via e-mail. If you have received a license file via e-mail, store it at a secure location on your disk.
• If you have already installed PTC License Server based on lmgrd and choose not to migrate to lmadmin, you must still update the license server with license codes compatible with Creo 4.0.
• If you have already installed PTC License Server based on lmgrd and choose to migrate to lmadmin, complete these steps before the migration:
1. Shut down any lmgrd service or processes running on the system.
2. Save the license.dat file from your existing license server installation to a secure location.
3. Uninstall the previous installation completely.
See Migrating from lmgrd to lmadmin, in the FlexNet Publisher License Administration Guide for more information.
