I installed X2C toolbox in Scilab 5.5.2. It have only four libraries Basic, Control, General, Math. It shows unable to load any blocks from X2C palette. It can’t open X2C demos. Additionally, X2C didn’t get installed in Scilab 2023.1.0. Also it is not available in Scilab 6.1.1. Looking for a solution. Thanks in Anticipation.

But I installed it from Module manager - Atoms from Applications menu. It should work right. Even it can’t open demo’s. Does anyone have faced this issue? When I open the Scilab, toolbox are getting loaded in console window. Atlast I am getting **“atomsLoad: The file ‘C:\Users\Gayathri\AppData\Local\scilab-5.5.2\contrib\siseli\0.5\loader.sce’ from (siseli - 0.5) does not exist or is not read accessible.”**  
Awaitng for solution. Thanks

No. This toolbox has not been updated by the author since Scilab 5.5.2. However, since Scilab 2023.0, by default all toolboxes are showing in Atoms GUI without any garantee of successful build (toolboxes with no updated binary package are built on-the-fly, sometimes it works, sometimes not). This update is the author’s work, particularly if the toolbox is associated to a commercial product.
