Here's my problem in detail. I got stuck. I appreciate if someone could help me out. I really need help!!!!! Thank you very much! 1 I installed unbuntn8.1+wine1.1.15. If I run wine notepad, the notepad window poped out, meaning Wine is installed properly. 2 I run wine winecfg opening wine set-up window ,select msvcrt,click add, edit to native, then apply, then I run wine notepad, the following error occured: err:module:import_dll Library msvcrt.dll (which is needed by L"C:\\windows\\system32\\notepad.exe") not found 3 Search ../.wine/drive_c/windows/system32/, there is a msvcrt.dll , if I run wine regedit, I could also see HKEY_CURRENT_USER\software\wine\DLLOverrides\msvcrt is set to native. Question: Why does not the Wine I installed support native DLL? If I change to wine1.1.16, the same proplem occures.
