This might be happening if your files were created outside of the installation process (i.e. not added by your setup).
Another cause for this could be if the files marked for removal are in use by another process. During the upgrade, do you encounter any "file in use" messages?
It somehow looks like I overlooked this part of your thread, please accept my apologies for this.looks like advanced installer used this folder to extract the msi and other file during installation.
