This is my command line, verbatim:
C:\Program Files\FlexSDK\bin>mxmlc.exe "C:\Program Files\FlexSDK\samples\explore
Loading configuration file C:\Program Files\FlexSDK\frameworks\flex-config.xml
C:\Program Files\FlexSDK\samples\explorer\explorer.swf (382417 bytes)
There's no SWF output anywhere. It's not in C:\Program Files\FlexSDK\samples\explorer, it's not in C:\Program Files\FlexSDK\bin, it's not anywhere.
So this is my introduction to FlexSDK.
See my reply on your previous thread.
Great!! It works now.
I followed your directions in recreating the environment as C:\Users\Public\FlexSDK then ran the compiler in the same way at it worked.
(The prior two write failures occured if I did C:\FlexSDK\ or C:\Program Files\FlexSDK\.)
Thank you again for all of your detailed assistance. Really generous.
