How do I start the xamarin form designer?
After launch, a pop-up message appears:
Preview requires Oracle Java JDK 8 (1.8) 64-bit or higher. Please install it and then set the Java JDK location in Xamarin Studio or Visual Studio.
But I am using version 1.8.
How to fix?
You are not using a 64-bit JDK 1.8 installation, you are using a 32-bit version.
Install 64 bit and change the path you highlighted:
C:\Program Files (x86)\Java\jdk1.8.0_101
to
C:\Program Files\Java\jdk1.8.0_101
