Recently my friend made aI bought to install a program the size of his Windows machine, and the computer gave an error on the death screen. After restarting the computer, he tried to start a new program and received the following message:

If you encounter this approach error on Windows, here are some ways to fix it!

Single Method – Make Sure Windows Installer Product Is Running

How do I make Windows Installer service automatic?

Scroll down the Services window and find the new Windows Installer service. Double-click the appearance to open the Properties window. On the General tab of one of our property sheets, click the Startup Type drop-down menu and select Automatic. Then go to the Service rating section.

Sometimes you can see this error when the installer service is actually disabled. You can enable it by typing Start, then Run, and then Services.msc. On newer versions of Just Windows, go back to the Start menu and type services.msc.

Then scroll down to Windows Installer and double click on it. Configure launch to enter manual mode, click Apply and Pause to launchservice.

You can also start the service by selecting Start, Run and typing Run in msiserver.

Method 2 – Remove MSIEXEC With Extension Only

Another strange thing that can happen is the creation of a second msiexec in your C: Windows system32 directory. By default, this expert directory should contain only one msiexec.exe file, but sometimes another file is written without an extension and is 4KB in size.

If yes, then you need to rename the additional information msiexec with the extension .OLD. After renaming, you can restart most of the Windows Installer services. Return to the Services section, right-click Windows Installer and select Restart.

Method 3. Modify The RPC

Sometimes a problem can be created by another service called RPC. Go back to the above Services section (Start, Run, Services.

Now go to the Login tab and in the Login section select: locale My system account “and select the” Allow this feature to interact with the desktop “checkbox. Then restart your computer and see if each issue is resolved.

If that doesn’t work, select the This account: radio button by clicking the Browse button. Find the network service by clicking OK. The password for this account is entered automatically, so it is not changed.

Restart this computer and see if the problem is resolved. Note that if it is shared, if you selected Local System Account, only this setting will be executed. This changes to NT Authority NetworkService only if the local system account is down.

Method 4: Reinstall Windows Installer Service

If that works, you can download and reinstall the Windows Installer service! Somehow ironically correct !? Do this if sometimes you don’t even see the service listed in the Services applet, or if all else fails.

You, probablyClearly, download MSIServer from the WinHelpOnline package. Once you’ve downloaded it, unzip it by right-clicking the .REG file and choosing Merge. Click Yes when prompted to confirm. Essentially, this adds the necessary A registry keys for the installation service to work properly.

Multiple Method – Install Latest Windows Installer

Finally, you can search for “Windows Installer” on Google and download the latest version from Microsoft. This ensures that you don’t use old ones that might conflict with technology, etc.

Hopefully one of these solutions will definitely solve your problem! If you did it differently, please leave a comment so we know how to do it! Thanks !
