I've completed the above using the 'Standard Uninstall' for the 32bit. I have then copied the files provided in the other posts x64 folder (see below) into the Mediaportal folder, however, the StreamedMP editor will not start. This is all on top of a clean install of Windows 10. Thanks for any help.
Do you have these files installed under c:\program files (x86)\team mediaportal\mediaportal:
SMPCheckSum.dll
SMPCheckSum_DotNet35.dll
SMPEditor.exe
SMPEditor.exe.config
SMPMediaPortalRestart.exe
