Why does %TEMP% resolve to a non-deterministic path of the form %TEMP\<digit>?

I have a Windows Server 2008 32 bit and when I'm typing %temp% it takes me to ..AppData\Local\Temp\1\ or ..AppData\Local\Temp\2 instead of ..AppData\Local\Temp

I've already checked the Environment Variables and they are ok.

I'm asking that because I have an application that's supposed to copy files to %temp%\my application and instead it copies the files to %temp%\1\my application

Does someone have a solution for that?
