Warning - AWS or Azure VM?
If you are using an AWS/Azure VM as your license server and are asked to provide the MAC address as your HostID, you will need to a static mac address prior to gathering the host info. The reason is, MAC addresses on Azure and AWS are not static by default and will require your IT Administrator to perform additional steps set a static MAC address.
If a static MAC address is not set, the MAC address will change when the server is restarted and subsequently, your license server will not start because the HostID in your license file will not match the HostID of the computer.
- These steps must be performed from the computer that will have the License Manager installed on it.
- Copy, paste and run the commands below in an Administrative Windows command prompt.
cd c:\
hostname >>AnsysHostInfo.txt
vol c: >>AnsysHostInfo.txt
getmac /v >>AnsysHostInfo.txt
- Browse to C:\ > send the file named AnsysHostInfo.txt to your SimuTech contact if needed.

When using a Linux machine, you are required to use a mac address as your HostID. MAC addresses on Azure and AWS are not static by default and will require your IT Administrator to perform additional steps set a static MAC address. This needs to be done prior to gathering the host info.
If a static MAC address is not set, the mac address will change when the server is restarted and subsequently, your license server will not start because the HostID in your license file will not match the HostID of the computer.
- These steps must be performed from the computer that has or will have the License Manager installed on it.
- Download the linx64.tar file in a browser or via a Linux terminal/shell with the wget command:
wget https://static.helpjuice.com/helpjuice_production/uploads/upload/image/9355/1696242/linx64.tar
- Untar the archive file:
tar xvf linx64.tar
- Run the GetLinX64Hostid utility:
./GetLinx64Hostid
- Complete the fields when prompted (customer number, company name, name, phone, etc)
- You may use the term NA in these fields.
- If you have multiple MAC addresses, contact your IT Administrator and confirm which will be the primary one used.
- While not common, if you will have multiple license servers you will need to repeat this process on those computers as appropriate.
- Return all created licserver.info files to your SimuTech contact so that all required license files can be created.
