A clean STS uninstall is a prerequisite to getting a second chance to install. Therefore, I’ve included it in this troubleshooting chapter. The steps you are most likely to miss are the manual ones. To uninstall STS from your server, follow these steps:
Click the Start button and select Settings Control Panel.
Double-click the Add/Remove Programs icon.
Select Microsoft SharePoint as shown in Figure 6-7 and click the Remove button.

When the uninstall process completes, stop IIS by opening a DOS command window and typing iisreset /stop.
When the system reports a successful stop, navigate to drive:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\50 and delete the contents of the folder.
Restart IIS by typing the command iisreset /start at a command prompt.
In SQL Enterprise Manager, verify that the STS database has been deleted.
Open Internet Services Manager, expand the Web site on which you installed STS, and manually remove any lingering STS subdirectories, including the MS_ProjectServer_PublicDocuments folder. A typical Default Web Site tree is shown in Figure 6-8.

Verify that the system has removed the STS database. A normal uninstall should remove the database. If not, remove it manually.
