When faced with a similar situation some time ago, I used MSXML to convert the data to a byte array before saving it to a file. You will need version 3 or higher.

To do this you would:

• Load the data with MSXML
• Set the node's dataType property to bin.base64
• Read the binary data from the node using the nodeTypedValue property
• To save the file you can use the ADODB.Stream component.

A few links on how the to this are below.
