Hi

i have creating a application in windows in vb.net. in that application, i am creating a object
AcroApp = CreateObject("AcroExch.App") while i am creating the object in the below error occurs.

Unable to cast COM object of type 'System.__ComObject' to interface type 'Acrobat.AcroApp'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{9B4CD3E6-4981-101B-9CA8-9240CE2738AE}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Give me a solution.

Thanks,
SIVASANKARAN G

Make sure you have installed Acrobat correctly and the COM components have been selected to be installed, otherwise this method will not work.
