Package installation Problem on client's Machine

My Clinet have Windows XP SP2. I have developed a system in VB6 with backend MS SQL server 2000.

On installation of my package on client's Machine i got 2 error messages :
1) The procedure entry point GetTextExtentPointI could not be located in dynamic link library MSDART.dll
2) Error occurred while registering the file Msado26.tlb

I ignored these errors & try to excecute my project file. It is working fine but problem is that in some module it gives error as "incorrect syntax near "-"". The same application is working fine in all other client machines where the operating system is WIN98, Windows 2000, Windows XP and not Windows XP SP2.

Is this problrm of MDAC ? As Windows XP SP2 has its own MDAC and not allows me to install MDAC 2.8.

Please Help me to solve this problem It is very urgent.

I think its the MDAC 2.8 because its not backwards compatible?
