kevin70,
In the past I have used a program called process explorer (procexp.exe)? you can download a zipfile at various sites - it may be a sysinternals
program? what it is - is a very detailed task and process manager - you need to be able to install it and run it somewhow on the hp box
if you can get it loded, you can search for the file name in all active processes and it will tell you the one(s) it is is being used by - then you can
kill that process and delete the file (hopefully!)
