On 10 winds and on the pirate 2 helped that
1) renaming the username from Cyrillic to English, on the 10th Vinda it's easy to do, look in the enet, then restart the comp
2) On the launcher yards 2 put compatibility with Windlos 7 (Not sure that it mattered, but still)
3)Launching a launcher only on behalf of the administrator
It helped me to rename the windows account into English and move the roaming folder to a freer drive. There is a user'appdata.
I decided to check the "Run as administrator" checkbox only required in the launcher and in rdr.exe
During the game, the same message popped up, saying it was impossible to save. The next launch was made as administrator and everything worked!
