Hi, the errors persist (Wine 1.3.37, ruby 1.8.7) Code: err:ntdll:RtlpWaitForCriticalSection section 0x1135e4 "?" wait timed out in thread 0026, blocked by 0000, retrying (60 sec) Probably all cmd commands give this error (error message repeats after 60s, doesn't stop). I tested echo, dir, cd, date, path, reg. While cmd commands don't work, launching applications works by giving the file path to the program or to a batch file. Example in Ruby: > puts %x[C:\\users\\username\\batch.bat] Off-topic, @jaspo: I used a workaround. I wrote the commands to a batch file and launched the batch file. If necessary, the batch file writes the results back to a text file that I then read into Ruby. You can find some code in the ImageMagick.rb here: forums.sketchucation.com/viewtopic.php?f=323&t=40720
