I am getting the below error during execution of archydro. "system runtime interoperservices com exception (0x80004005): error HRESULT E_FAIL"
I tried all options available on internet to solve this but no luck.
What is the cause of these type of issues? Is this related to application or os ? What is the perfect fix if it is caused by arcgis/hydro or os ?
I am using windows7, 64-bit, Arcgis10.
