Can I use the Remote Assistant with a K100D Super?
No, the application doesn't work with the K100D Super. According to the information on the official website, Remote Assistant is working only with K10D and K20D.
You can check this information on the following website: http://ricoh-imaging.ca/en/support/digital/remoteassistant_k10d_mac
The only thing available for the K100D is a firmware update: http://www.ricoh-imaging.co.jp/english/support/digital/20060808e.html
