I am using intellij idea 13.0. When I am trying to checkout from subversion I am getting error
Cannot load supported formats: Cannot run program \"svn\": Cre
Basically, what IntelliJ needs is svn.exe. You will need to install Subversion for Windows. It automatically adds svn.exe to PATH environment variable. After installing, please restart IntelliJ.
Note - Tortoise SVN doesn't install svn.exe, at least I couldn't find it in my TortoiseSVN bin directory.
