You can set up new temp dir and restart installation process.

**1.** Create a new Temp directory.

eg:
E:\Temp
**2.** Set temp environment variable as

set TEMP=E:\Temp
set TMP=E:\Temp
**3.** Start the installer from the same prompt as

java -jar fmw_12.2.1.4.0_wls.jar
OR

Installer can be started using the command

java -Djava.io.tmpdir=E:\Temp -jar fmw_12.2.1.4.0_wls.jar

This issue comes because there is not enough space available in your default temp folder. If you are on windows and there is a drive with more space available then you can create temp folder there and use that for installation. For specifying a different temp folder you can go to environment variables and change the temp and tmp variables to point to new location.

not sure about your point but mine was an item before opening pop up Installation Location and was a kind of java.lang.NullPointerException at oracle.jdeveloper.model.ApplicationContent.getInstance(ApplicationContent.java:62

I went to and got in:

C:\Users\MyUserName\AppData\Roaming\JDeveloper\systemSomeVersion\

backed up o.ide folder and deleted it, relaunched IDE and now it plays ok again
