Windows 8.1 Installation Error

Installation worked fine in Windows 8, but after upgrading to 8.1, starting getting this error. Reinstalling didn't help. This path is the home directory for "NT Authority\System".
Any thoughts?

Hello!
C:\Windows\System32\config\systemprofile is treated as your HOME doirectory for some reason... http://www.coderanch.com/t/517573/java/java/System-getProperty-user-home-unreliable looks related. But this is a system folder you can't write to - thus the problem.
I'd suggest passing a different user home to WebStorm - just add -Duser.home=<your preferred location> to bin/WebStorm.exe.vmoptions file
Also, the config/system files location can be explicitly changed in bin/idea.properties file, idea.config.path, idea.system.path, idea.plugins.path and idea.log.path options
Thank you Elena, it looks like that should work. Good detective work on finding that link; I couldn't find the right thing to Google on. Seems like it might be a JVM thing. Weird.
Thanks for your help.
