I recently got a new computer and I downloaded Minecraft. On my old computer I had a minimap called VoxelMap that was incredibly useful. I tried to get the minimap again and I needed to download Java. When I downloaded Java and tried to open a jar file the error message,
"Unable to install Java
There are errors in the following switches:
"C:\Users\My Name\OneDrive\Desktop\The file I was trying to open";.
