Orcad Capture - Error 5004 (Netlist export / Error intializing COM property....)

Morning,

I don't fire up Orcad very often, so I can't say when this issue started happening. When I try to export a netlist of a design, I get the error:

ERROR(ORCAP-5004): Error initializing COM properly pages: Invalid pointer

I've tried the solutions presented in this post, but neither of them work. The "regsvr32 orpxllite.ocx" results in a further error:

"The module orpxllite.ocx failed to load.
Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent DLL files.
The specified module could not be found"

I also tried running the provided debug .TCL script from that post, but it gives no return at all.

Running in Admin mode does nothing to change the result, same error.

I'm running 16.6.-S086 (v16-6-112HJ)

Any ideas to fix this?

Thanks,

Rafael
