Hi again,
Downloading to specified directory is the main functionality in the scheduler so I guess your problem is environment related.
the following message:
Error opening D:\Global RCP\To Global\SALUCRO\ for writing ((0x3) The system cannot find the path specified.
says that the user SYSTEM (on which the scheduler is run) is not able to find specific file/dir.
Can you check the folder D:\Global RCP\To Global\SALUCRO\ with right-click->Properties->Security to see if SYSTEM is listed on the directory (or directory above) ? What users/groups are listed there?
Can you try to create new local directory like C:\temp\ and use it in the scheduler. Does it work or not? And check the access rights for the SYSTEM user as above.
