Okay I checked this out and C:\users\aleer\locals\locals~1\temp\6uu0004.tmp is actually point to C:\Users\aleer\Local Settings\temp where the 6uu0004.tmp file does not even exist.
I guess it's possible that this file is being created and then it disappears once I get to the command prompt.
I'm not sure what the problem is...
Discovered the directory the temp file was being created in wasn't owned by my user. Changed the owner of the directory and now it works.
