Many people have this question “Does Sharepoint gets installed on Vista?”. The answer is yes. I installed MOSS on my Vista machine yesterday successfully.
All you need to install Sharepoint, WSS or MOSS, on Vista is
- You must select the Advanced option during install.
- If you want to run on SQLExpress, manually install it first. Get it here.
- You have to manually enable IIS7 with the proper options. Web Management Tools and World Wide Web Services. Enable at least the following options in IIS.
Download Vista Helper file from here, and run the setup file WssVista.msi.
