Issue

Installing USB Drivers Failed
LOYTEC NIC Driver Installer
Error Installing USB Drivers: Could not pre-install Drivers
Product Line
TAC Vista
Environment
Vista Server
Cause
The failure occurs due to insufficient administrative privileges, even when logged in as a domain administrator. The installer requires local administrator rights to successfully install USB drivers.
Resolution
To resolve the issue, follow these steps:
- Locate the installer executable file (.exe) for the Loytec NIC software.
- Right-click on the file and select “Run as…”.
- Choose the local administrator account (not the domain admin).
- Proceed with the installation. The USB drivers should now install successfully.
Additional Notes
- This issue is commonly encountered in environments where domain policies restrict driver installations.
