Configuration aborted due to non-existing MCD..?

Hi folks,

Do anybody have an idea what does this means (the configuration seems OK and the MCD of DB2E is existant and seems OK, I checked it via MI_MCD as well):

[20071029 15:30:08:664] E [MI/Deployment ] ERROR_MESSAGES: Installation file does not exist. Upload the file.
