Hope you can help me, I have multiple PC with the same error while trying to add printer from client computer:

The process cannot access the file because it is being used by another process

It occurs on XP x32 and 7 x64 on random client and printer, some client can add some print while other cannot add this printer but it's ok with another one.

Did anyone has had this problem or have an idea to resolve it?

We have client on IPrint 5.6 or 5.93.
