Error HRESULT E_FAIL has been returned from a call to a COM component.

[Mark]

"It consists of a single .NET assembly which is compatible with both 32 and 64-bit machines, and has no external dependencies."

This is a stated attribute of Essential PDF, but it is not particular true. There is an external dependency for Microsoft.mshtml.

Anyhow, I am receiving the following error which I have not been able to resolve. I have read other posts on these forums and elsewhere that lead me to believe this is a permissions or security-related matter.

Are there any other recommended solutions to this problem?
