Hello,

This is a known issue. The installer requests the location to store the files, but actually doesn't use that location for anything. The files are deployed to system directories instead.

May I also comment that in my case the only DLL's installed are in SysWOW64, which I assume are the 32-bit DLL's. There are no DLL's installed in System32.

64-bit OPC client applications get an error "Interface not supported" when attempting to connect to OPC servers.

32-bit applications work as expected.

This does not seem to be working as expected.

The redistributable installed is the latest one from the OPC Foundation web site (opc-core-components-redistributable-x64-20150731)

Thanks for the feedback.

I have managed to get the 64-bit client working by copying the OPC dll's from SysWOW64 into the same folder where our 64-bit executable is located. I must say that I don't really understand why it works but I assume there's a valid reason. So far so good.

I have the same issue. There are no files at all.
