Error 1618 Fix

When you attempt to run Windows Installer, or a program dependent on it, you may have experienced the 1618 error. This error means that you have more than one instance of Windows Installer running and so the process cannot continue. I finally made it. I was able to install AppFabric for Win Server 2012 R2. I am not really sure what exact change made it worked. I saw and tried many many solutions from various websites but above solution of making changes to Registry - 'HKEYCLASSESROOT'worked (please think twice before making changes to Registry on production environment - this was my demo environment so I just went ahead.

The following error is encountered either during installation/removal, in the Product's Installation Log file, or in Window's Event Logs:

'Error 1618: 'Another installation is already in progress'

SOLUTION

This Error indicates that the Windows Installer Service is currently being utilized for another installation or update at this time. Alongside other program's Installations, Windows Updates can also occupy the Windows Installer service and will thus need to complete prior to running another installation.
However, if a previous installation was unsuccessful and did not close properly, you can end the Windows Installer Process manually:

Reboot the computer and try installing again
If the error returns, attempt to find any applications currently installing and close them
If unable to find an application running updates, open Task Manager and navigate to the 'Processes' tab
Select 'Show processes from all users' if it is not already.
Locate and end any 'MSIExec.exe' entries you see.

After these steps, attempt the installation once more.

CAUSE

The Windows Installer process can only run one installation at a time. Complete the other installation or wait a few minutes for the background installation taking place completes.

Having its pros and cons, Skype is a must-have tool these days – we rely on it heavily to achieve effective communication, and the app tends to serve this purpose well.

But what if Skype installation fails thanks to the mysterious error 1618? Does this mean the good old app is forever beyond your reach?

Of course not. The problem in question can be easily resolved if you know what to do.

Why Does Skype Error 1618 Crop Up?

The issue in question appears when you are trying to perform several installs at once.

For example, if you can see the 1618 error code when installing Skype:

you might have accidentally started Skype installation twice;
another installation process is being executed at the same moment;
your Windows 10 is installing updates.

Therefore, to keep the error message ‘Another installation is already in progress’ at bay, you should:

be careful when installing programs;
avoid parallel installations;
wait for the current downloads/installations to complete before proceeding with another install.

If your Skype keeps having issues despite all the precautions above, move on to explore our solutions to the persistent 1618 error.

Well, it is time to begin our journey. But first, you should perform a backup.

Indeed, we strongly recommend you to back up your personal files before launching an attack on the error in question.

As a precaution, use any of the following tools to your advantage:

Portable backup devices (e.g. flash drives, compact disks, etc.)
Cloud solutions (e.g. OneDrive, Dropbox, Google Drive, etc.)
Special backup software (e.g. Auslogics BitReplica)

Besides, we guess it would not hurt to create a system restore point:

Windows logo key + S -> Type restore into the Search box -> Create a restore point
System Properties -> Create -> Describe the restore point you want to create -> Create

You can always go back to it if things do not go as planned:

Start -> Control Panel -> System and Security -> File History
Recovery -> Open System Restore -> Next
Select the restore point you want to return to-> Next -> Finish -> Yes

By the way, you can use the instructions above to roll back your PC to the latest working restore point – that will undo recent system changes. Try out this manoeuvre as it is reported to be capable of fixing the 1618 Skype error.

1. End the Microsoft Installer Process

To tell the truth, a little patience is required when it comes to installing programs on your computer: for example, you are supposed to proceed with a Skype install only when no other installation processes are being executed. However, we understand you might need to use the app without any delay. In such a case, you will have to end the msiexec.exe process manually.

For this purpose, use Windows Task Manager:

Ctrl+Alt+Del -> Task Manager
Processes -> select the MSIEXEC.EXE process -> Click End Process
Install Skype

Has the issue been resolved? If not, hurry up to give the following method a try.

2. Run Skype as an Administrator

If the error 1618 prevents Skype installation from being a success, you can try the following workaround:

Skype setup file -> Right-click on it -> Run as administrator

Did it work?

If you still encounter the ‘Another installation is already in progress’ message, keep working your way down.

3. Install Windows Updates

If your PC is acting weird (which includes generating the 1618 installation error), your system might need updating.

Make use of the built-in Windows Update feature:

Windows logo key + I -> Update and Security -> Check for updates
Let the available updates come through
Wait for the installation process to complete
Restart your PC

Now try to install Skype on your computer. If the frustrating 1618 error code is still here, consider tweaking your Windows registry.

4. Edit Your Registry

Whatever it takes, be extremely careful when editing your registry – even a minor mistake can damage your system and cause your PC to go haywire.

Therefore, we strongly recommend you to back up your registry before editing it:

Windows logo key + R -> Type regedit.exe into the Run box-> Enter
Registry Editor -> Select the registry keys and/or subkeys you want to back up -> File > Export ->Choose the location and name for the backup file -> Save

Now you can perform the necessary changes:

Windows logo key + R -> Type ‘regedit’ into the Run box
Navigate to HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionInstaller
