Welcome to PerlMonks!

It's customary when asking a question here to post the snippet of code with enough context to describe the problem.

In this case, it seems as though this is more a Windows problem, as when you try to overwrite a read-only file in Windows without using Perl, you'll get the same prompt.

EDIT: Thanks Athanasius for pointing out that chmod() doesn't do what I thought it did on Windows (although it did reset the ro bit on a shared drive I was testing on). I then tried with Win32::File::SetAttributes() to no avail. However, I did finally come across a way.

# unset the RO bit on a file
system("attrib -r filename.csv");

#... do writing to file

# change file back to RO
system("attrib +r filename.csv");

I have serious doubts if that will have any effect if it's NTFS permissions preventing writing though...

If Win32::OLE doesn't have the capability to change a file from read-only, you can use the built-in chmod() function:

chmod 0777, $file;
# do stuff that writes to file

[download]

The 0777 mask will make the file read, write and executable (r, w, x) by anyone who has access to the system. 0755 will make it r/w/x the owner (which might not be you), and only readable for everyone else.
