Running FSSERVICE -i to install Fileshare as a service fails with the following error:

"FSS005-S Fileshare Service failed to install."

User Account Control in Windows Vista, Windows 7, and Windows Server 2008 extends to the Command Prompt and prevents users (even those with administrator privileges) to run a command to install a program as a service.

You need to open a Command Prompt that is run as administrator to install a program, such as FSSERVICE, as a service.

To run FSSERVICE command from the Command Prompt:

1. Right-click on the Command Prompt shortcut
2. Click on Run as Administrator
3. Issue the FSSERVICE command

You should then get the following message:

"FSS004-I Fileshare Service installed successfully."
