https://bugs.winehq.org/show_bug.cgi?id=40613 --- Comment #22 from Anastasius Focht <focht(a)gmx.net> --- Hello tim, --- quote --- RUNAS don't work with start /d ... wine runas /trustlevel:0x20000 start /d 'D:\' dzclient-1.7.85.exe --- quote --- you didn't quote properly hence all parameters after 'start' are interpreted as belonging to 'runas' command. On modern NT-based Windows, 'start' is a builtin of Windows command shell. Wine's external 'start.exe' program is a Win9x legacy and doing more harm than good, especially in WoW64 prefixes. I would even consider removing this - but that will likely break many crappy scripts. Doesn't work in 64-bit WINEPREFIX: --- snip --- $ wine runas /trustlevel:0x20000 "start /d c:\\ notepad" RUNAS-Error: start /d c:\ notepad could not be started 2: File not found. --- snip --- Works in 64-bit WINEPREFIX: --- snip --- $ wine64 runas /trustlevel:0x20000 "start /d c:\\ notepad" --- snip --- I would suggest you use 'start' properly as 'cmd.exe' builtin which avoids the aforementioned issues. --- snip --- $ wine runas /trustlevel:0x20000 "cmd /c start /d c:\\ notepad" --- snip --- In your case it would be: --- snip --- $ wine runas /trustlevel:0x20000 "cmd /c start /d D:\\ dzclient-1.7.85.exe" --- snip --- Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.
