Bonjour,

Pouvez-vous attacher vos ordinateurs au même modem et créer de cette façon un petit réseau?

Non pas du tout 

If you still have access to your old computer you can locate the download file for Sage 50 2018. 

C:/Users/Public/Public Documents/Sage Software/Simply Accounting/Download/SA_2018CP1.exe  if you also installed the updates for 2018 they will show as SA_2018xCPUP1.exe.

You may also locate the installer files:

C:/Sage/Sage 50 Accounting Installer Files - CDN Release 2018.x/Launch.exe

Hope this helps
