Because my hard drive is nearly full, I find I don't use the (full)IIS7 and uninstall it to release hard drive space in my vista computer.
However, after that, I can't do many download installations through 'Microsoft Web Platform Installer 4.0", for example, download and install webMatrix 2.
I install the IIS8 express, I still can't do many download installation through MWPI 4.0, even I can't uninstall the MWPI from my computer. thanks advanced
