Hi,

I have created a base64 encoded pkcs7 renewal request. I submit this
request to the Certificate Services using
pCertRequest->Submit( CR_IN_BASE64 | CR_IN_PKCS7,
             _bstr_t(pkcs7Request).copy(),
             NULL,
             _bstr_t(strCA).copy(),
             &nDisp )))

I keep on getting the error "CR_DISP_INCOMPLETE".

Could you please help me with this ?

1. Does the certificate which has to be renewed need to be in the last
month of its validity period ?
2. I have installed a Stand Alone Certificate Services, is renewal
supported by Stand Alone CA ?

Thanks and Regards,
