Visual Studio 2015 RC Community will not install, says it is already installed

Question

As the title implies, I am not able to install Visual Studio 2015 RC Community, and I keep getting the following errors. For the record, I am on Windows 8.1 Professional.

Answer 1

I have the same issue then installing update1 to the visual studio 2015 community.

install error, link to the image and text:

Visual Studio Professional 2015 is currently installed on this machine. Please uninstall Visual Studio Professional 2015 and retry.

In past i installed plugin Visual Studio 2015 Installer Projects that didn't work with VS 2015 community and work with VS 2015 profession.

This recipe was:

1) Launch RegEdit

2) if win32: Select key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DevDiv\vs\Servicing\14.0" if win64: Select key "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\DevDiv\vs\Servicing\14.0"

3) In that key/subkey, you must create two new subkeys: "professional" "vscore"

4) In each of the subkeys you have just created create a REGSZ value (=string) with the name "Install" and value "1" (yes: "1" is a string!)

Now to address the problem in VS 2015 community had to rename or delete a folder in the registry "professional"

Before community folder, picture

Before professional folder, picture

vscore

After professional folder, picture
