Calendar Magic requires the installation of Microsoft's Visual Basic 6 runtime files in order to run successfully. If not already installed, they may be downloaded from many Web sites, for example:

When installing on Windows Vista or Widows 7 for the first time, if you wish to transfer your personal settings by copying the file calmag.ini from a Windows XP (or earlier) based installation of Calendar Magic, use a text editor to update the Printer Name entry in the [Form 29] section of calmag.ini to:
Printer Name = (Default Printer)
This will avoid potential problems with changes in assigned printer names.
