Lamp Bulbs Cannot Be Changed After Creating a Custom Head in Depence (Also Applies to Depence R4)

Issue Description

After creating and using a Custom Fixture Head in Depence, the lamp (bulb) cannot be changed.

This includes:

• Changing the lamp type has no effect

• Modifying lamp parameters does not apply

The same issue occurs in Depence R4, and the solution is identical for Depence R4 and other versions.

Root Cause

This issue is not a bug in Depence.
It is caused by insufficient system permissions in the Windows operating system.

When using Windows Home Edition:

• System permissions are limited

• Depence cannot properly write or update lamp-related data

• As a result, lamp changes fail

Solution (Important)

✅ The Windows operating system must be one of the following:

• Windows Pro

• Windows Enterprise

✅ Depence must be run using an Administrator account

Only under these conditions can lamp changes be applied successfully.

Recommended Steps

1. Verify your Windows version

   • Recommended: Windows Pro or Enterprise

   • Windows Home is not supported for this function

2. Log in using an Administrator account

   • It is recommended to run Depence directly from an administrator account

3. Follow the procedure shown in the reference video

   • The video demonstrates the correct workflow for changing lamps
