Problems archiving in windows 7

I amusing lotus nOtes 8.5 in my desktop with Windows 7. I create an archivingg definition, but when I try to archive I recieve the messe “Notes Error: It is not possivle to create te file”. The archiving file isn´t even created. I gave full rights access to my user in the directory where I entend to archive. What do I have to do? I think it´s a problem with windows 7 security, but can´t find a solution. thanks
