msiexec.exe belongs to the Windows Installer Component and is used to install new programs that use Windows Installer package files (MSI). This program is important for the stable and secure running of your computer and should not be terminated.
msiexec.exe is the executable for the windows installer. This should only be running while you are running an installer. It's also a Windows System File and should be in a system directory. If it is then this application is safe.
just another annoying windows component
it is a hacker file there are to files called msi 1 is windows file 2 is a hackers file for bf2 and more games msi is dangerous if it looks like this msi.exe do not tick the box on your firewall if it looks like this msiexec.exe you are ok to tick it
I have been trying to delete CTFMON.EXE from windows 2000. When it is being blocked the "Installer" window trys to force a function everytime I open internet explorer. It locks up the computer until I go to Task Manager to "End Task" (installer)?

Norton AV = Malicious script detected. Object - Windows Script Host Shell Object. Activity - Run. Your computer is halted and needs to do something about this scriot. File - MsiExec.exe. What do you want to do? Action - Stop this script(recommended). NOTE!!! Clicking OK does not stop/remove this script, nor can it be quaranteened!! ALSO: This happened when using Add/Remove Programs to remove eEye Digital Security Blink. The remove attempt does not work.

This file resides in the %windir%\Windows\System 32 directory and is ESSENTIAL for installing and uninstalling programs which use .msi installer package instead of self-extracting execution. If this program is deleted or becomes corrupted by virus or other means, you cannot add or remove programs. See the accompanying link for remediation.

Microsoft Installer. if it has a installer-like icon, it is mostly safe, but if doesn't have an icon, then definately a malware. scan using BD or the like to make sure. and yes even if its in system32 folder makes it a malware (even though that's the original location). it is also in system32\dllcache.
This is the command line API to the winows installer libraries. msiexec will run whenever you install, modify, or uninstall a program. In a corporate environment, it may be triggered to run in the background. In a personal environment, it should not be running unless you are installing something (as stated before).
Absolutly NEEDED per Windows
I have noticed a spelling variation between the legitimate msiexec.exe and malware versions. If the letters of the file are all lowercase there is a good chance the file is safe. All capital or a variation of capital and lower case is mostly likely related to malware. For example MsiExec.exe or MSIEXEC.EXE

Don't know what to think. Was playing a game when I noticed a slight lag (low fps), and hearing my hdd activity; lights were flashing. Thought somethings up. So checked it out in TM and this .exe using 100% CPU usage. Went like this for a long time, and I didn't see any windows update icon, or noticed any download activity beforhand. Weird...
It's used for installation. If you see it taking some space in memory and you don't remember starting any installs/updates/uninstalls, end it immediately, because it might be hijacked to silent-install rogues and the like.
all lowercase is an actual microsoft service, you can get by with stopping the service until you plan on doing a lot of software installation. if you're anything like me, i download a new prog or 2 every day. Continue that routine, but don't run the installs until yo "start" the "msiexec.exe". if you're completely comfortable with starting and stopping background services, then do what pleases you. To the previous comment, it's not used for automatic updates (other than the installation part, which your UAC (user acces controls) should be set to authorization before installation.
msi is next generation of exe to install auto application. It is just a batch commands compact in one container to run one by one or standard to execute batch by Microsoft. Before Windows 2000 Microsoft uses exe to install program but soon they realize it is vulnerable to many security risks. So, they set there own standard. Unlink Open Sources deb packagesor RPM such as red hat package manager. It is the same. If you are facing trouble with installation of any application. Just vist MS website. Download Latest Installer and there you go.

After uninstalling Logmein.exe I found it running in the background. Obviously serves some function to do with installing and uninstalling. I uninstalled Logmein because, even tho I had disabled it in my startup list, it still insisted on opening every time I booted up. I really hate that.

msiexec.exe is not a malware. it is a program used by windows to install and uninstall programs in your computer. based on my knowledge, msiexec.exe is used for updating programs such as adobe reader. i scanned this file with avast 5 and it did not detect anything harmful in this file. if you are having problems with msiexec.exe, your pc might have a virus running in the name of msiexec.exe or it got infected by trojan or a virus. to prevent further problems if your anivirus detects it as a malware, move the file to quarantine, do not delete. just don't run any update using this file.

Msiexec.exe is the wndows installer file that is used for updates as well as any installations on your computer. often with it is working in the background and you arenot installing a probram it is updating your windows system or looking for updates to your windows system or preparing them to tell you they are ready or just installing them in the background without you knowing. so wait and see if you are asked to restart because of updates or you get an update related message you will know.

msiexec.exe is a process necessary for your computer to run .msi installations and uninstallations. If you corrupt this file or remove it, you will be horribly defiling your system. As for those people that are having problems with it, have you installed anything recently? Several viruses and malwares hide their process behind the same name. So if you thnk you are having a problem, then its time to scan your computer.

msiexec.exe in windows\system32 is safe. However, had a malware version attempt to run, from an "Unknown Publisher" from C:\Users\*username*\AppData\Local\Temp so be sure you know where it's coming from before allowing it..
I don't really know alot about it. It just happen for the first time to me 10mins ago. it wont not stop so i put it in safe mode with intrent and it ask me about systerm restore and I cllick conutine and i let it do its thing and every thing looks good so far. PS i did not allow it to come in
Found the file in my personal folder. Downloaded itself, and would automatically attempt to run. Windows requested administrative access, but clicking "no" would just pop up another window. Found in C:/users/nick/msiexec.exe. I understand there is a legitimate file with the same name, but this particular one was malware.
Hey guys/Gals. I've had the same problem, i figured it was the brouser trying to update info. a day or so after i clicked yes a screen popped up saying i had viruses and needed to buy this anti virus package to get rid of it. I could not say no, for the screen woudl keep popping up. I tried to uninstall it but everything i did a screen would come up saying..what program do you want to open this? Had to restore in SAFE mode. Virus gone but flashing blue bar remained. Did full scan, Avast found it and removed it. Comp. works fine...for now.
Usually it is a normal file, but not always! One way to tell is to go to the process in the task manager, and open the location. Right click on it and show the properties. If it is by Microsoft and is all lower case, it is fine. If it is by any company other than microsoft, it is most likely malware. Look up Malwarebytes and dowload their free trial. They will remove the file for you if it is a dangerous version. I use Norton, but it didn't think it was dangerous; Malwarebytes did, and I just found out that they were right, because the real msiexec is still in its proper place, not gone
msiexec.exe is a Windows installer program. In my case, cause turned out to be my Anti Virus program updating in the background automatically, may well be that the other instances of the program running were other applications on your system updating themselves.
It's the windows installer. what the hell is wrong with you people? delete this and you've deleted the WINDOWS INSTALLER. This program may execute malware but that doesn't mean this file is infected.....
This file is not inherently a threat. This file, as many have said before, is responsible for handling the extraction and setup of .MSI installer packages. .MSI = MicroSoft Installer. Msiexec.exe = MSI execution handler. If this is showing up as malware, it is because your system is infected and the msiexec has been corrupted by a virus or malware.
safe, basic installer

Was Sie bei msiexec Problemen tun können

Ein aufgeräumter Computer ist die beste Voraussetzung, um msiexec Probleme zu vermeiden. Hierzu sollten Sie einen Malware-Scan durchführen, Ihre Festplatte aufräumen (mit cleanmgr und sfc /scannow), nicht mehr benötigte Programme deinstallieren, Autostart Programme überprüfen (mittels msconfig) und Windows Updates automatisch installieren. Denken Sie immer daran ein Backup oder zumindest einen Wiederherstellungspunkt zu erstellen.

Bei einem konkreten Problem überlegen Sie bitte, was Sie als letztes getan bzw. installiert haben, bevor das Problem das erste Mal auftrat. Nutzen Sie den Befehl resmon, um diejenigen Prozesse zu ermitteln, die Ihr Problem verursachen. Selbst bei schwerwiegenden Problemen sollten Sie anstatt einer Windows-Neuinstallation lieber eine Reparaturinstallation oder ab Windows 8 den Befehl DISM.exe /Online /Cleanup-image /Restorehealth ausführen. Damit wird das Betriebssystem ohne Datenverlust repariert.

Zur weiteren Analyse haben sich folgende Programme als nützlich herausgestellt: Der Security Task Manager untersucht den aktiven msiexec Prozess auf Ihrem Computer und zeigt anschaulich was der Prozess macht. Das bekannte Tool Malwarebytes Anti-Malware sagt Ihnen, ob die Datei msiexec.exe auf Ihrem PC lästige Werbung einblendet und so Ihren PC ausbremst. Solche unerwünschten Adware Programme werden oft von einer Antivirus Software nicht als Virus eingestuft und deshalb nicht erkannt.
