2. System Requirements and Pre-Installation Hygiene
The most common cause of a "bad" installation is attempting to install the software on an unprepared system. lmgr.exe ) as suspicious
2.1 Hardware Prerequisites
- Storage: v12 requires approximately 8-10 GB of free space. However, for optimal performance, an SSD (Solid State Drive) is highly recommended over an HDD to reduce library loading times.
- RAM: Minimum 8 GB (16 GB recommended for complex flowsheets).
- OS: Windows 10 (64-bit) is the standard. Windows 11 support was improved in later builds of v12, but checking the specific "System Compatibility Matrix" in the release notes is crucial.
2.2 Software Environment Cleaning Before inserting the installation media, the system must be cleared of legacy conflicts:
- Remove Legacy Versions: If upgrading from v10 or v11, use the "Aspen Tech License Manager" uninstaller and the main uninstaller. Do not manually delete folders, as this leaves registry keys that corrupt the v12 installation.
- Microsoft Visual C++ Redistributables: Aspen HYSYS relies heavily on specific VC++ runtimes. It is best to let the Aspen installer handle these, but if you have corrupted existing versions, run a repair on your current VC++ installations via the Windows Control Panel before starting the Aspen install.
- Antivirus Exclusions: Create an exclusion folder for the installation directory. Antivirus software often flags licensing executables (e.g.,
lmgr.exe) as suspicious, halting the installation midway.
