Execution Error

HI all,
Please help me to get rid of this error, I have written a demo instance provider and I have
Successfully compiled the mof file as well as the registeration mof.
But whenever I fired command to the instance provider  like gi, ei , ni etc.. its show me the error that

CIM_ERR_FAILED: ProviderLoadFailure : <../../ProviderName.dll>
Provider is not a CMPI style provider. Cannot find ProviderName_Create<mi-type>MI symbol.

Please give me valuable suggestion to solve this as well as the reason of occurrence of such type of error.

Thanks and Regards
Manish
