This message can occur when booting @RISK if:
There are two entries in the DTOOLS.INI file, which is located in the WINDOWS directory, that control how TopRank launches Excel during bootup.
The relevant section of this INI file looks like:
[EXCEL]
EXCEL32=C:\Program Files\Microsoft Office\Office
EXCEL16=C:\Excel5
EXCELEXE=Excel.exe
The EXCEL32 entry should point to the directory which contains the 32-bit Excel executable (i.e. Excel 7.0 or higher). There should not be a trailing backslash in the entry. The name of the executable file (e.g. Excel.exe) should not be appended to the end of the path.
The EXCEL16 entry should point to the directory which contains the 16-bit Excel executable (i.e. Excel 5.0 or earlier). There should not be a trailing backslash in the entry. The name of the executable file (e.g. Excel.exe) should not be appended to the end of the path.
The EXCELEXE entry should have the name of the executable file. Usually this will be "EXCEL.EXE", but occasionally system administrators will rename the Excel executable to some other name.
