When trying to view a report in Dietplan, various error messages are displayed and the program shuts down

Version 9 of Adobe Reader was released in July 2008 and causes these problems when Dietplan tries to use it to view its reports. You can click here to download the previous Version 8 of Adobe Reader, which does not have these problems or you can switch to using Dietplan’s internal report viewer instead. From the Edit menu, select Preferences and Report viewer. Then click the Built-in viewer button and OK

After that, if you prefer to use Adobe Reader 9 to view and/or print your reports, use the Save button on the report viewer page and open the saved pdf file with Adobe Reader outside Dietplan.

Update 6.30d5 can be downloaded from the Support page and, when installed, will detect the presence of Adobe Reader 9 and automatically switch to the internal viewer.

When Dietplan6 starts, it is minimised on the Windows taskbar and will not open

This occurs if Dietplan has previously been closed by shutting down Windows while Dietplan was minimised. To fix it, ensure that Dietplan is not running - by logging out of Windows if necessary - then open the folder

C:\Program files\Forestfield\Dietplan6\database

using Windows Explorer and double click on sqlite.bat. In the command window that opens, after the sqlite> prompt, please type

delete from privil where privkey = '$owner';

There must be single quotes around $owner and the line must end with a semi-colon. Then press the ENTER key. If you get another sqlite> prompt without any errors, close the command window and try running Dietplan6 again. The problem has been fixed in the update to Dietplan6 (version 6.11k or later) that can be downloaded from the Support page.
