Windows Installer error: Windows Installer could not be accessed

I just Crysis and I try to install it, but when I try the Windows Installer appears and stays there for half an hour then says that Windows Installer could not be accessed. Help, please. (64-bit version of Windows Vista)

Well, I found the solution for this:

  • Log your computer as an administrator.
  • Click Start and then click Run. (or alternatively, you can press windows + r on your keyboard)
  • In the Open box, type cmd and then click OK.
  • At the command prompt, typemsiexec.exe /unregister, and then press ENTER.
  • Type msiexec/regserver, and then press ENTER.

It fixed for me.

    You could try to go to the MICROSOFT website, go to KNOWLAGE database and in the search bar, try the search for WINDOWS INSTALLER. Look for any version that is newer than the one you have. If this fails, try searching on GOOGLE. You can also try to do an update to WINDOWS VISTA.
