• "Error 1719. Able to access the Windows Installer Service"when you install programs.

  After spending the last week every night trying to get some software installed (and of course the search for remedies in probably all available forums), I let go and post this request for assistance. But first my story:

  I have lived the last week suddenly my Neat Receipts software does not recognize my scanner more. Trying to reinstall the software, I came across the error that Windows Installer could not be started. That's when I started first for solutions. I was surprised how many solutions I found (but more redoubled practically the same thing), but none did it for me. At this point, I was always under the assumption that it is a problem of the Neat Receipts software.

  Then after another night of frustration I could not pass my trial version Office 2010 plus a sort of license error. I was a little surprised that the trial version which abruptly ended without giving me the opportunity to enter a license key (I got wrong), but doesn't bother too much because I liked the product and had noticed last week as well as Office 2010 is already officially released and I decided to buy it. After spending about $300 and a successful upload, I tried to install it.

  And here my saga continues. First I got the message that I couldn't upgrade my trial version and need to uninstall. Uninstall with the uninstaller routine does not work (windows error message install), but I could uninstall it using the Windows-Install-Clean-Up utility. Now, I can start the installation process, but after being nearly halfway through the installation, I again get the error of Windows install the Windows Installer Service cannot be accessed (Error 1719). It is roughly the same error that I got at the beginning, when I tried to reinstall the software, Neat receipts. So, it seems not to be a misapplication of Neat receipts or Office 2010, but a windows problem.

  The frustrating thing however is that after spending all hours searching online for solutions, the only thing I've discovered is that I am in good company (i.e. There are many others have reported the same problem), but none of the solutions work. Just to be safe, do not for get the same Advisor I tried already several times, let me enumerate what I've done so far:

  1. I am logged on as administrator

  2 - I started the Windows Installer service

  3 - I ran SCF /sannow (no problems found)

  4. I not saved and re-entered the msiecec with / opt and/regserver. I did so explicitly for BOTH (!) msiexec programs, one in the system32 folder and the one in the sysWOW64 folder

  5. I tried to repair Windows 7 boot from the windows 7 installation DVD and run the option repair (no problem found)

  6. I tried to pass the parameter registry WOW64 (for MSIServer) from 1 to 0 (I found this in one of the suggested solutions) [and later again back to the original value 1]

  7. I tried to 'force' windows to ignore the msiexec for 64 bit (in the system32 folder) by renaming and by identifying the msiexec for 32 bit 9 in the sysWOW64 folder) and update the path regsever C:\Windows\system32\msiexec.exe \V to C:\Windows\syswow64\msiexec.exe \V

  8 - I disabled my firewall and antivirus

  9 - I did everything above in many variations with reset (both the save option - reboot)

  -in fact, I could do things more I can't remember.

  Unfortunately a recovery is not an option most, because I guess I tried too many things and my view of the possible return is a point in which my computer was already in place...

  I tried to involve as well a representative of Microsoft support explaining my dilemma, but only made e-mail a generic response on this same forum (great customer service!).

  While I was actually pretty happy in the last 4 months with my new Windows7 (and thus Office2010), I am now reaching the point where I fell like throwing finally the towel and kiss goodbye to Microsoft. I was seriously considering to move to Apple before decide me in February favor some cheaper hardware to continue with Microsoft and the new Windows7. But this experience not being able to fix my computer after spending nights in the search for solutions and not be able to get support from Microsoft disgusts me.

  Now I wonder if there is someone out there who could help me out here...

  Of course, the .msi applies only to installers .msi, which was my mistake for which I apologize.  Regarding a clean installation, the fact remains that you have faced this anomaly for several days, a clean install, despite the pain, would be a distant memory now.  This is my personal opinion, not Microsoft, they me disavowed a long time ago, in all cases MVPS have nothing to do with Microsoft, although the price is published by Microsoft, it is awarded for the caregiver, or in this case try to help others.  It is good that I can at least allow you to vent, it's better out there that maintenus kept bottled upward, no matter how hard it seems to fix the problem, it will be resolved in your favor by subsequently, one way or the other.

  In pursuing the side of permissions of things you can try that if you wish.

  This example may or may not work for you, with your program?

  "It seems that the"Run as Administrator"command gives you administrative privileges only, and they are not enough to install Java (and OpenOffice, by association). To work around this problem, you must actually connect to an administrator. Open a command prompt with admin rights by clicking Start, type cmd in the search/run box, hit CTRL-SHIFT-ENTER. At the prompt, type:

  NET user administrator / Active: Yes

  Then disconnect from your regular account and record as an administrator, you should be able to install the program. When you are finished, open a session to your regular account and, for security reasons, disabling the account administrator for assistance:

  «net user administrator / active: No.»

• Can't install Itunes, get an error that the Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode"

  OP: Install problems Windows

  I tried to install iTunes, but he said that "the Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode or if Windows Installer is not installed properly. Call support personnel. "They gave me similar messages by other programs I've tried to install as well.

  Because I was not running Windows in safe mode in time, I assumed that the installer was not installed correctly. So I tried to download from here: http://www.microsoft.com/downloads/en/details.aspx?familyid=5A58B56F-60B6-4412-95B9-54D056D6F9F4&displaylang=en

I'm running a Vista Home Premium 64 bit, and I 2.38 GB of available RAM, so I don't think that the lack of memory is the problem here. What should I do?

  I was looking around and I found this: http://www.vistax64.com/vista-installation-setup/96680-repair-windows-installer-service-vista-all-versions-2.html

  Ladies and gentlemen,

  Currently, I get the following error when I try to install any program in the system:

  The service runs. I tried to unreg and regserver via safe mode.  But the error persists. The register indicates the path to the correct image for the msiserver. The service seems to work very well.

  I can't locate a download of version 5 of the MSI installer. All the references found are versions 4.5 and earlier versions.
