I'm trying to compile a small executable in Win64 that makes use of the IFilter interface.

Registry read accesses are okay, the CoCreateInstance on IFilter and QueryInterface for an IPersistFile on the IFilter instance pass with ok results, but the first use of the interface (an IPersistFile.Load) dies with a RunError(1). This is using the fpc 2.2.2 & ActiveX that comes with Lazarus (where IPersistFile is defined).

Is COM support functional in 2.2.2 Win64? Are there known issues?

Eric
