I am having trouble upgrading to the newest version (from version 3.26). After make install, this is what happens:

"C:\temp\html-parser\HTML-Parser-3.45>nmake install


Microsoft (R) Program Maintenance Utility Version 6.00.8168.0

I have enabled full control for everyone on the HTML\Parser directory. I do not know what else to do or what is causing this error. Any help is appreciated. Thanks.
