It is recommended to never use any path names that contain spaces with ADF. That is, the ADF installation folder must not contain any spaces. For this reason C:\Program Files\ is not a suitable location to install ADF into. It is also not recommended to run ADF from a folder with spaces in the path name, e.g. "C:\Documents and Settings\Default User\My Documents\", although it might work in some cases and might fail is others. The same applies to names with spaces, for example "Iron Chloride.adf".
