MSN Messenger setup has failed with error code ‘1603’

(Updated 4/7/05)

Folks, we think we have fixed most of the 1603 issues in 7.0.  Go here and try the released build.

(Update 3/18/05)

Several folks have contacted me to who have tried these steps listed here, but who are still having prroblems.  We’re working on improving the steps. 

When you attempt to install MSN Messenger the setup may fail with one of the following errors:

An error occurred during the installation of assembly component.


HRRESULT: -214702894


An error occurred during the installation of assembly ‘Microsoft.Windows.Networking.RtcDll,type=”win32”,version=””,publicKeyToken=”6595b64144ccf1df”,processorAchitecture=”x86””. Please refer to Help and Support for more information. HRESULT: 0x80070002.


This is the dreaded 1603 error.


The number one cause for this is having anti-spyware running when you try to install MSN Messenger.  To test this, turn off or disable your anti-spyware application and try installing Messenger again.


If that fixes it, great!  Turn the anti-spyware application back on and enjoy the newest version of Messenger.


If that didn’t solve the problem it could be one of following:


Insufficient disk space


You may not have enough disk space to complete the install.  You should have at least 50 MB of free disk space to install Messenger.  It isn’t that Messenger needs 50 MB when installed, rather that during the installation process Messenger decompresses files and stores them temporarily on your hard drive.  So, make sure you have plenty of free disk space before installing MSN Messenger.


If you need to free up some disk space, try running the Disk Cleanup Manager.  To launch the Disk Cleanup Manager:


  • Click Start, click Run, type "cleanmgr" and then click OK.
  • Select drive C: from the list of drives (or the drive your temp environment variable points to).
  • Click OK. The Disk Cleanup Manager will analyze the selected drive to determine the amount of space that can "cleaned up".


Note This may take a couple of minutes, so be patient.


  • In the Disk Cleanup window, click the Disk Cleanup tab.
  • Select the following check boxes:
    • Downloaded Program Files
    • Temporary Internet Files
    • Temporary Files
    • Temporary Offline Files
    • Offline Files
  • Click OK to delete the selected file types.
  • When you are prompted, click Yes to confirm the operation and start the process.


The temporary folder is encrypted


If your computer is running Windows XP or Windows 2000/2003 you have may enabled encryption for the %temp% folder on your computer.  If the folder was encrypted, you must temporarily turn off encryption on the folder before you install MSN Messenger. To turn off encryption:

  • Click Start, click Run.
  • Type in "%temp%\..\" and hit Enter to open an Explorer window.
  • Click on the Temp folder to select it.
  • Right click on the Temp folder and choose Properties.
  • In the Properties window, click General.
  • Click on the Advanced button to open the “Advanced Attributes” window.
  • In the “Compress and Encrypt attributes” section, uncheck “Encrypt contents to secure data”
  • Click OK twice to save changes and close the Properties window.


Re-register the MSI installer files


Windows XP SP2

  • Click Start, click Run.
  • Type "msiexec /unregserver" and press Enter.
  • Type "msiexec /regserver" and press Enter.


Windows XP SP1 and Windows 2000 SP3 and later versions


Windows 98/ME


Windows 2000 SP2 and earlier

Okay now try installing MSN Messenger again.  Try to install Messenger again:


For MSN Messenger 6.2 click here.

For MSN Messenger 7 Beta click here.

    I\’ve been getting the 1603 whenever I try to install the Live Messenger 8. What should I do since I have a Windows Vista Basic on my computer??

    The specified module could not be found

  4. Rose says:

    i tried everything for mesenger 7.5 and i still get the error 1603!
    what do i do?

  5. Andrew J says:

    Fantastic! I had this issue My Computer > Properties > Advanced > Environment VariablesI had TWO temp folders set up – BOTH pointing to the same location. This is presumably where the MSN Messenger became confused over which to use.I removed one (it didn\’t matter which, they both pointed to \\Documents and Settings\\%username%\\Local Settings\\Temp) and then MSN Messenger installed without issue.

    Hi.. I get the same error "Installation failed with error 1603". However its seems not to be any of the issues seen above. Prior to the installation failing I get "Error writing to file:C:\\WINDOWS\\system32\\sirenacm.dll. Verify that you have access to that directory.". I looked around in several forums but looks like not too many folks have come across this issue. Any suggestions? A brief background how I got here. I used to have msn messenger 7.5 working on my computer. After I installed Windows Media Player version 10.0, messenger started freezing up, freezing everything else up like internet explorer. I rolled back to Windows Media Player 9.0 but the problem did not go away. I finally had to uninstall msn messenger. Now, it won\’t install.

    Sadly… this sucks. If I can\’t install MSN Messenger (and other things happily install) I\’m led to think that someone, somewhere is being too clever by half. 7.0 and 6.2 refuse to install with the same 1601 / 1603 errors, despite trying all the aboveMy machine is a fairly standard… WinXP Pro -> SP1 -> SP2 and all the patches.I also can\’t installed the Tabbed MSN toolbar with the same error.Y! messenger installed without a hiccup….

    Hello,I, like most of you, had the same problem (error 1603), and tried all of the above to no avail. Nevertheless, I was able to fix "my" problem.First I\’d like to mention how I came about to acquiring this problem. It all began when I was trying to make a Video CD with Nero. I was getting an error message saying I didn\’t have enough disk space for the temporary files while creating the VCD. The problem for me was that I have two partitions and my C:\\drive (where my temp folder is located) was too small. So, I went to "My Computer\\Properties\\Advanced\\Environment Variables" and changed my Temp folders to point to a new location on my D:\\ drive which has pleanty of space. After this change, I was able to create my VCD with no problems so I decided to leave these changes in.That was my mistake…. After trying all of the above I began to suspect that the messenger install program might be looking for the Temp folder at it\’s default location so I changed it back to the way it was and my messenger installed like a charm!I realize that you may not have made these changes to your system, but perhaps it\’s worth taking a look. After all, what have you go to loose? Right?I suggest you check and see if your temp folders are pointing to their default location which is:C:\\Documents and Settings\\%username%\\Local Settings\\Temp(tip: If you don\’t see this folder within windows explorer it means you have to go to "Explorer\\Tools\\Folder Options\\View" and select "show hidden files and folders")I hope this helps some of you or at least provide you with some insight as to where YOUR problem resides.Good luck!Regards,Enrique J.
