The Windows installer error 2908 are all failures in writing to the Windows registry.
First thing to do is open the Windows registry with "regedit" (run from a command window 'Run as Administator') and set a RegistrySizeLimit DWORD value of 0xffffffff (eight f's) in this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
create it anew if not already present.
Also, check that you have not disabled support for .NET 3.5sp1 -- done from "appwiz.cpl" (also run from a command window 'Run as Administator') and the "Turn Windows features on or off" from the menu on the left. In the Windows Features dialog that opens--make sure there is a blue selection box made for the Microsoft .NET Framework 3.5.1 entry. If not, set it and OK out. If already set, just cancel out.
Restart the computer!
Disable UAC and any Anti-virus/anti-malware program!
Make another attempt at the installation--are you working with DVD media, or the downloaded installer? Either way, you need to make sure to run the installation as an Administrator. When clicking on the ESRI.exe, or on the extracted Setup.exe, use the right mouse button and "Run as Administrator".
Post back if still stuck.
