You are right, in the computers that the worksheet works fine there is
Office XP Pro 2002 installed (MSOWC.DLL). In the computers it did not work
there is Office XP Pro 2003 installed (so there is not MSOWC.DLL).

Any way to automatically install that DLL in a computer that does not have
it, or make the worksheet automatically use the new version of MSOWC.DLL
(example MSOWC10.DLL)?

Thanks
