Procedure To Fix Windows Installer Service Could Not Be Accessed

Windows 7 offers some of the best features for its users. That is why, over 50% of the desktop OS users in the world use Microsoft Windows 7. Agreed, it is one of the most solid Windows OS that Microsoft has developed till date. However, there are many problems that can occur in Windows 7, and annoy users often.

Sometimes, when you try to install any third party program in Windows 7 that uses an MSI file as the installer, you may see an error message on the screen saying: Windows Installer Service could not be accessed. Though the error message alarms most users, there is no reason to panic. There is an easy solution for the issue, and Omni Tech Support shows you how to fix the same.

  • First, click on the Start button located at the lower left corner of the desktop screen and enter Run in the search box.
  • When the Run dialog box opens up, enter cmd in the text area, and click on the OK button. It will open the Command Prompt window on your computer screen. 
  • If you are using the 32-bit version of Windows 7, enter %windir%\system32\msiexec.exe /unregister in the pop-up box, and hit Enter. This command will unregister the msiexec.exe file in the system, which is located at Drive:\Windows\system32 directory.
  • After that, enter %windir%\system32\msiexec.exe /regserver in the command prompt window and hit on the Enter key. This time, it will re-register the msiexec.exe file in the system directory.
  • If you are using the 64-bit version of Windows 7, enter %windir%\syswow64\msiexec.exe /unregister and %windir%\syswow64\msiexec.exe /regserver in the command prompt window, in the same sequence as mentioned above. Here, your msiexec.exe file will be located at Drive:\Windows\system64 directory
  • When done, type in Exit in the command prompt window, and press the Enter key. Restart your system to allow the changes take effect. 
When your computer reboots, it will be possible for you to install programs that use MSI installer files. The above mentioned steps work perfectly for Windows 7 computers. However, if you are not sure how to operate on command prompt, contact the Omni Tech support team for assistance, before something worse happens.
