Can't reinstall .Net Core SDK after removal "product is already installed"

Question

I uninstalled .Net Core SDK with "programs and features". When I now try to install the .Net Core SDK again, I get following Error Code:

Error 0x80070666: Process returned error: 0x666

Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.

Assuming you are on Windows, Can you go to

C:\Program Files\dotnet\sdk

Manually remove the SDK you are looking to reinstall.

I dont have any dotnet folder anymore. The SDK was completly removed. – LowkeyFlex Feb 22 '17 at 20:02
Can you go to your command line and type "where dotnet". This will tell you if you have an existing SDK installed (And the location). – MindingData Feb 22 '17 at 20:09
Welp. Where is just a standard CMD command (https://ss64.com/nt/where.html). So... Something bigger going on I would think. – MindingData Feb 22 '17 at 20:32
Yeah. That doesn't look good. Going to reinstall Windows i guess – LowkeyFlex Feb 22 '17 at 20:49
