hi all,
I am facing very typical issue. My project is using com dlls. It is running successfully in test environment but on another machine it is showing an error.
"Unable to cast COM object of type 'prjMultiPath.clsMultiPathClass' to interface type 'prjMultiPath._clsMultiPath'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{A8DF4195-AB53-11D5-BFE6-00D0B79CF5A9}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). "
Kindly help.......

What have you done to solve this problem so far? Have you googled this error message?

Advice: Post "really urgent" is unlikely to get you any more help than not doing so. This isn't a tech support site, it's a help forum. I think for most people everything they post is "really urgent" because it's what they are working on at the moment and they are stuck. Something that is much more likely to get you help is to ask for help properly (http://www.catb.org/~esr/faqs/smart-questions.html).

Well the COM component on the other machine doesn't support that interface. Make sure that component versions are the same in both environments.
