partially resolved by renaming buldozer_x86.exe to buldozer.exe ... I saw that it worked even changing to run in the arma3 directory .. even tried to install it on another computer that I use as a server, and the same result ... no buldozers crash is seen moving vegetation .. by pressing f1 you see the 4 fields, but no writing and mouse movements or other buttons dsnt work, rename to use bulldozers x86 and it works ...
