That does sound ridiculously slow! I'm not sure why it's taking around 10
minutes to delete a file. Deleting files should be a simple thing for the
NSIS installer to perform (it's not like it has to decompress the files,
which might at least explain why extracting the new version is slower, but
it shouldn't be that slow!). Do you have anything like anti-virus software
that might be checking each file on access before allowing the file to be
deleted (or created)?

I'm afraid not, sorry. If you click on the "Show Details" button during the
installation you can see what it's done/doing (the installer launches
"silent" installations of the Microsoft Visual C++ Redistributables, which
may take a long time without any feedback in the Nmap installer), but we
don't currently create an install.log file (I suspect you'd see exactly the
same information though).

Thanks for letting us know, I'm not sure why it's going so slow, but I doubt
it should take days to do anything. Are other applications (with high CPU or
disk access) experiencing similar performance problems, or just the Nmap
installer?

Rob
