SigmaStudio won't start on Windows 10


I am preparing to migrate to Windows 10 and have it set up as dual boot with Windows 7.

I discovered that .net3.5 needs to be installed separately on Windows 10. On doing so I installed SigmaDSP v3.15 x64, but it won't start.

It is showing the message as captured in the attachment.

Without SigmaDSP I can't/ won't migrate to Win10.

Kindly look into this and advice.
