A “stream” is generic term for information coming in (Read Stream) or going out (Write Stream). This can be from various source (Memory = DataStream, Network = TCPStream), but the most common problems are found around reading and writing files (FileStream).

The stream write error is usually caused by:

1. Invalid file name structure
2. Destination is full or what you are saving is larger than diskspace available.
3. You don't have permission to write the file.

1. Check the C:\ Drive and/or the drive Cyrious is installed
2. Ensure there is enough free space on the Drive
3. Have customer clear some space on the drive and test
4. Empty the contents of the temp folder.
