Acces to a file that is locked by another process

I am writing a package to process perfmon logs. The issue I have come across is that the perfmon process holds onto the log file and SSIS fails because it wants to exclusive read access. Is there any way of getting SSIS to not take an exclusive read on the file.

I can read the file in notepad fine but not SSIS.

check by changing the isolation level of package by default its serialiazable
