Hi, The last week, I occured a error. I designed a VB program using a ADOConnection of ADO2.5 connected to Access97 database in WinME. The same application I runned in another machine which installed WinXP and Office2000, there all things is ok. The machine I occured a error was installed WinME, Office2000. The error description was "Class is not found".
After I installed the MDAC_typ.exe that including ADO2.5, but the error still occured.

Are there someone occured this error like me? Please tell me how to treat this?
