Install ember@1.13.13 on Windows 7 and it keeps hanging on the extract of bower

I'm trying to "npm install -g ember@1.13.13" on Windows 7 and it keeps hanging on the extract of bower. I've tried clearing the npm cache and the bower cache but it still hangs. I'm installing that specific version of ember as that is the version required for the project I'm involved with. Here is the command window output;
