Windows 7: Windows Installer Problem

Today my Window 7 decided it wasn’t going to install any new MSI packages because another installation was already running. A few minutes in the company of Mr. Google turned up a number of possible fixes – most of them for Vista.

 I tried several but the one that worked was  …

  • Disable the Windows Installer Service
  • Reboot
  • Set the Windows Installer Service to Manual
  • Reboot
  • Run the installation again.

When I re-ran the installation it told me that MS Tools for Applications 2.0 ENU was still being installed & gave me the option of rolling the install (of MS tools … ) back. Once I accepted the option the rest of my MSI install completed OK  🙂
