The error may also result in the Error 1935 or 1309 etc. if not fixed immediately. Error 2908 occurs during the Microsoft Office 2010 installation due to corrupt registry, missing TrustedInstaller file, outdated drivers, and outdated version of Microsoft .Net Framework etc.
The error halts the installation and doesn’t let you begin with it again unless you fix it. So, here are the simply workarounds which will let you fix the error 2908 in some time and reinstall the Microsoft Office 2010 smoothly.
Make sure that no Microsoft Office application viz. Outlook, Word, Excel, PowerPoint etc. is running before you perform any or all of these steps.
Open Command Prompt from the Start menu> All Programs> Accessories. If you are using Windows 7, click the Start button> type “cmd” in the Start Search bar> right-click Cmd.exe and click Run as administrator. In Command Prompt window, type “Scanreg /Fix” and hit Enter. When the command is finished running, it will prompt you to reboot your computer. If you are not prompted, then also reboot your computer.

Disable your antivirus/firewall program and then restart the installation. The antivirus or firewall program considers TrustedInstaller.exe as a malicious file and thus removes it from your computer. The missing TrustedInstalled.exe file causes the error 2908 during the installation of Microsoft Office 2010.

If the file is missing, you will need to restore it. Open Command Prompt and type this command “takeown /f drivename\windows\filename” and hit Enter. So here to take ownership of the servicing folder first in order to restore the file, you will type “takeown /f c:\windows\servicing” and hit Enter. In order to grant the full permission and restore the missing file to the directory, type “icacls c:\windows\servicing\grant administrators:F” and hit Enter. If prompted, restart your computer. If not prompted, close Command Prompt.
You can begin the installation again. if the problem persists, you may need to restart the TrustedInstalled service. Open Command Prompt again and type “net start trustedinstaller” and hit Enter. If this is not recognized as a valid command, then type “net start Windows Modules Installer” and hit Enter. Restart your computer only if prompted, otherwise don’t. Start the Microsoft Office 2010 installation again and it should finish smoothly.
If the problem persists, repair the Microsoft .Net Framework. Go to Add or Remove Programs (Programs and Features in Windows 7) in Control Panel, click Microsoft .Net Framework> click Change/Repair> click Repair. Follow the on-screen instructions and it repair the program. Restart computer if prompted. Begin with the Office installation again.
Update all device drivers from their respective manufacturers’ websites. Disable unnecessary programs and services running at the startup.
