Hi,  
I am trying to install the [Communication Toolbox](https://atoms.scilab.org/toolboxes/comm_tbx/0.3.1/) in Scilab 2025.1.0 in an offline environment. It requires the Helptbx and Apifun dependencies. Helptbx installs without any issues, but when I try to install Apifun, I receive the following error:

```
atomsInstall("C:\temp\apifun_0.4.3-61-bin.zip")
at line 53 of function atomsDESCRIPTIONread ( C:\Users\ole\AppData\Local\scilab-2025.1.0\modules\atoms\macros\atoms_internals\atomsDESCRIPTIONread.sci line 113 )
at line 182 of function atomsInstall ( C:\Users\ole\AppData\Local\scilab-2025.1.0\modules\atoms\macros\atomsInstall.sci line 198 )

atomsDESCRIPTIONread: The file "C:\Users\ole\AppData\Local\Temp\SCI_TMP_13684_31511\.atoms\tmp_1750744902\apifun_0.4.3-61-bin\DESCRIPTION" is empty.

```

I think the problem is that the latest binary of the Communication Toolbox is for 6.1.x. How can I obtain a version for 2025.1.0?

Thank you!  
Ole

Hello, welcome to Scilab’s Discourse !

I just recompiled apifun and comm\_tbx (helptbx was already availaible as binary) for Scilab 2025.1. You should be able to download and install offline all 3 packages.
