TL;DR
Some MSI installers on Windows 11 may hang indefinitely during "Computing space requirements" if a network drive is mounted via ASUSTOR EZ Connect (version 1.2.4.11260). In this case, KensingtonWorks 3.1.18.0 would not install until the EZ Connect drive was unmounted.
While installing the KensingtonWorks 3.1.18.0 software using an .msi file on Windows 11, the installation got stuck at the step “Computing space requirements”, despite having over 200 GB of available disk space.
Analysis through installation logs
Generating a detailed installation log using:
msiexec /i "kensingtonworks_3.1.18_1732754957.msi" /L*V kensington.log
clearly indicated that the installation stalled at:
Action 09:56:11: CostInitialize. Computing space requirements
The CostInitialize step calculates the required disk space on all connected volumes, including network drives.
Root cause: ASUSTOR EZ Connect network drive
The system had a network drive mounted using the ASUSTOR EZ Connect 1.2.4.11260 software. Although the regular command to check disk space in PowerShell 7 responded promptly.
wmic logicaldisk get Name,Description,FreeSpace
The MSI installation logs explicitly showed that the ASUSTOR EZ Connect-mounted network drive caused the installation to hang.
This mounted network drive through EZ Connect prevented the installer from proceeding beyond the disk space checking step.
Solution
The practical solution involved unmounting the network drive using the ASUSTOR EZ Connect software interface. After unmounting this network drive, the MSI installation immediately continued smoothly, and KensingtonWorks 3.1.18.0 was successfully installed.
This method was chosen based on clear evidence from the log analysis that the installation stalled specifically at the CostInitialize step when checking mounted volumes.
