Java path to Program Files folder in windows 64bit

Question

i`m trying to get the default Program Files folder on java. When I use:

 System.getenv("ProgramFiles")

It returns "C:\Program Files" instead of "C:\Program Files (x86)"

I can add manually +(x86) but if the user will use 32bit system it will be the wrong folder.

Answer 1

You should be using

System.getenv("ProgramFiles(X86)")

You can find the full reference on Wikipedia.

Answer 2

This is the correct answer for 32-bit Program Files directory

System.getenv("ProgramFiles(X86)")

However if a programmer is looking for the 64-bit Program Files folder but running a 32-bit JVM, System.getenv("ProgramFiles") will return "\Program Files (x86)\" as a side effect of 32-bit compatibility. In some cases, a programmer will still want the 64-bit ProgramFiles directory. This solution has its flaws, but will usually work...

System.getenv("ProgramFiles").replace(" (x86)", "")

Which is only marginally better then

System.getenv("SystemDrive") + "\Program Files"
