# Install BSF4ooRexx on Windows 64-bit

Java is a prerequisite for installing BSF4ooRexx. Java's and ooRexx's bitness must match (i.e. both must be 32 bit or both must be 64 bit)

First, check if you have either Java, ooRexx or both installed already.

Java

- Open the command prompt (how?)
- Enter "java -version"
- If the output contains information about your java version, java is installed. If the information contains "64-Bit", you have java 64-bit installed. If it does not, you have java 32-bit installed. If the output does not contain information about your java version, java is not installed

ooRexx

- Open the command prompt (how?)
- Enter "rexx -v". If ooRexx is installed, some information about the installed version will be displayed (you will also see if you have the 32 or 64 bit version installed). Otherwise it is not installed

Check the following table to see what to do next
