System requirements
You must check whether your system meets the hardware, software, and operating system requirements to install the HCL Local License Server (LLS) product.
Hardware requirements
You must ensure that the system where you want to host LLS meets the following hardware
requirements:
| Hardware | Minimum requirement |
|---|---|
| Disk space | 256 GB |
| RAM | 8 GB |
| Processor | 2 GHz - 2 Cores |
Note:
The LLS 5.2 installation does not mandate 256 GB of free disk space
and can operate with substantially less available storage. However, allocating higher disk
capacity is recommended to support log rotation and to ensure sufficient space for long-term log
retention.
Software requirements
If OpenSSL is not already installed, you can download and install OpenSSL 3.x or a higher
version on your host machine. You must set the PATH environment variable to include the
installation path of OpenSSL.
Important:
- OpenSSL is required if you are generating a self-signed TLS certificate as part of the LLS installation process.
- OpenSSL is required if you plan to use a third-party TLS certificate with encrypted tls key file.
- LLS supports only the full version of OpenSSL. The Lite version is not supported.
- Connect with your local IT to get the right version of OpenSSL without any vulnerabilities.
- You can ignore OpenSSL requirement, if you plan to use a third-party TLS certificate without encrypted tls key file.
Note:
If OpenSSL cannot be installed on the target machine where LLS is to be installed, due to
policy or security restrictions, you may generate a self-signed certificate on a different
system where OpenSSL is available. Once generated, the certificate and key files can be securely
transferred and used during the LLS installation process. There is no requirement for the
certificate to be created on the same machine as the LLS installation, as long as the
certificate parameters are correctly defined.

LLS supports installation on the following operating systems:
| Operating system | CPU Architecture | Versions |
