Hello, I'm trying to play with a friend in multiplayer, but we can't get the same version with or without mode, his launcher indicates version 4.0.21 (bb43) but once on the menu it has version 4.0.21 (d179), on my side no problem so any idea??
 
Either he has mods enabled, has edited game files, or has a corrupted installation.

In the latter two cases have him do a full clean re-install:

- move any valued save games elsewhere, and user empire designs.txt from /Documents/Paradox Interactive/Stellaris/ if you have made any custom empires or races."uninstall" in Steam-Stellaris
- manually delete both the Steam/SteamApps/common/Stellaris AND Documents/Paradox Interactive/Stellaris folders - **In particular you need to make sure there are no files or folders left under either the Steam Stellaris or Documents Stellaris locations, before installing again.**
- re-install game in Steam, run a Steam Verify when done.
- add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.

All the best!
