Errors when installing and uninstalling programs in Windows Safe Mode

If the tool from Microsoft is applied, but you still cannot remove the program, or some of the recently installed programs are registered in autoload and prevent normal system startup, then you You can try to uninstall the application through Windows Safe Mode. This method is useful in cases where the software developer himself recommends deleting the program in Safe Mode.

What is Safe Mode, all ways to start the system in Safe Mode, the nuances of entering Safe Mode for Windows 10, the differences in actions for previous versions of the OS, Windows 7 and Windows XP are discussed in the corresponding article. As part of the current record, we will not dwell on this in detail.

Well, we entered Safe Mode, open the Programs and Features menu in the Windows Control Panel, find the application that we want to uninstall, click the Delete button and .... we get the following error:

Unable to access the Windows Installer service. Perhaps not installed Windows Installer. Contact for help.

Unable to access the Windows Installer service.

Moreover, if we try to start the Windows Installer service manually, we will get another error

Failed to start the Windows Installer service on the Local Computer.
Error 1084: This service does not start in safe mode (Safe Mode)

Unable to start the Windows Installer service on the local computer

Troubleshooting Windows Installer Startup Errors

To start the Windows Installer service, you need to make changes to the Windows registry.

Open Windows Registry Editor

  • Run the Run utility by going to Start - All Programs - Standard (in Windows 10 the Run utility is in the System Tools directory), or by holding the Start keys on the keyboard (on some keyboards, it is marked Win) and R
  • In the opened window we drive in the command
    regedit

    and click on the Enter key

In the registry editor, go to the following branch:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\

If you will work in a safe mode with loading network drivers, then further actions need to be done on a branch:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\

Here, on the left side of the registry editor, you need to create another partition, calling it MSIServer

In the created section, in the right part of the registry editor, with the created string parameter (add a new string parameter if it does not appear automatically) in the Value field write Service

MSIServer branch. Service Parameter

Save the changes and close the registry editor window.

Now you can start the Windows Installer service. This can be done in two main ways, which we will consider below.

Start Windows Installer service from the command line

Open the command prompt:

  • On Windows XP, Windows Vista and Windows 7 systems, this can be done from the Start menu - All Programs - Accessories - Command PromptCommand line on behalf of the Administrator in Windows 7
  • On Windows 8, Windows 8.1 and Windows 10 systems, you can right-click on the Start icon on the monitor screen and select Command Prompt
    Command line on behalf of the Administrator in Windows 10

In the console that opens, enter the command

net start msiserver

And press the Enter key. The console will give you a message stating that the service has started successfully.

You can not enter the command manually, but simply run the bat file created earlier, which is attached to this article: msiserver_start 

Run Windows Installer from the Services menu

Open the Services menu in Windows:

  • We right-click on My Computer (in Windows 7, the explorer is simply called Computer, in Windows 10 - This computer), here we select the Management (item (in Windows 10, this item is located along the Additional - Management path). Now, on the left, open the Services and Applications menu and click on the Service option.
  • Or we follow the path Start - Control Panel - System and Security - Administration - Services

Further in the right part of the window we find the service named Windows Installer, click on it with the right mouse button and click on Run

Starting the Windows Installer Service

That's all. Now you can safely remove any application in Windows Safe Mode with both third-party uninstaller programs and the standard Add or Remove Programs utility in the Control Panel.
