Temporary disabling of antivirus software during a fresh installation can prevent the "fix" from being blocked by false-positive security flags. 4. Official Sources and Support

When installing or updating Optiplanning, users frequently encounter specific software bottlenecks. Here is how to fix them. Fix 1: The "Sentinel HASP / LDK" License Error

Navigate to the Optiplanning root installation directory (usually found under C:\Biesse\Optiplanning\ or C:\Program Files (x86)\Biesse\ ).

Many users successfully download the software only to face execution errors related to the license manager. Update the Sentinel HASP Drivers

Download the latest from the Thales Customer Support portal.

Optiplanning relies on a physical USB security dongle or a digital software license container (such as Thales/Gemalto Sentinel). Even if your download is successful, the software will not open without the proper driver fix. Step-by-Step Driver Repair:

Verify the post-processor formats in the "Tools/Import/export options" menu to match your specific Biesse machine model. How to Get Official Support For a direct "download fix" (such as a missing or a corrupted patch), you should use the official Biesse Parts & Service

Log into your official Biesse Parts / SOPHIA Portal account. Navigate to the software download matrix associated with your machine's serial number. If your corporate maintenance contract is active, request a direct FTP link or cloud download token from your regional Biesse software support technician to ensure you receive the correct build (e.g., OptiPlanning v4.0 or v5.0) matched to your CNC numerical control version. Step 2: Resolve Windows Permission and UAC Blocks

Reinsert the USB dongle into a USB 2.0 port (some legacy keys fail to read properly in blue USB 3.0/3.1 ports). 2. Database Corruption and Optimization Failures

Connect your computer directly to the router via an Ethernet cable during the download. 3. Resolving Installation and Setup Errors

Log into your official Biesse Parts account to access software updates linked to your machine's serial number.
