Issue

When attempting to use an i1Pro2 spectrophotometer, the following error appears:

i1Pro not connected (Error -5, 'E')! or i1Pro not connected (Error -5, 'D')!


Cause

This error is typically caused by an incorrect or missing i1Pro2 device driver. As a result, Windows is unable to recognize the instrument.


Solution

Option 1 – Reinstall the i1Pro2 Driver Included with neoStampa

  1. Close neoStampa.

  2. Run the following installer as Administrator:

C:\Inedit\neoStampa\Required\i1Pro2

  1. Complete the installation.

  2. Open Device Manager and verify that the i1Pro2 is recognized correctly.

  3. Restart neoStampa and test the connection again.


Option 2 – Install the X-Rite Driver

If the issue persists, install the official X-Rite software package, which includes the required drivers.

A compatible version is available here:

Note: X-Rite has discontinued support for some older versions of the i1Pro2 software. If the latest version does not resolve the issue, install a previous supported version if available.


Verification

After installing the driver:

  • Confirm that the i1Pro2 appears correctly in Windows Device Manager.

  • Open neoStampa and verify that the device is detected without errors.
