Sky GO on Computer completely stuck

[scps]

About 2 months ago, sky go on my computer started having problems connecting the application (not internet issues) I have had to uninstall and reinstall numerous times but keeps happening. Works then stops, then starts again - sometime within the same hour - but very frustrating. 

I uninstalled and reinstalled but it looks like it has not installed correctly as now the app will not open - comes up with errors. 

I then tried uninstalling and that doesn't work either as message saying missing "uninstall" exe file and I can't reinstall as on trying that another error message comes up. 

Does anyone have any ideas how i can remove the sky go installation so that I can try installing it again?
