HI stasys44,
Thanks for the report about win7 CompactOS and USB boot.
Will be fixed in next version.
About v2, no it was never updated to use wim install of xp.
You can translate v3, to your language by right click on title bar and select "Create Lanuguage File".
The new dll can be edited with ResHacker.
Or if you prefer, you can rename "Lang\1049.dll" to "Lang\language.dll"
than you will have always a Russian interface.
