Vista - The Windows Installer Service could not be accessed (Error 1719)

For a couple of weeks, I've been unable to install or uninstall any 64-bit applications that uses the Windows Installer. I alway get the message "The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance." Installing and uninstalling 32-bit applications that rely on MSI does work correctly.

- I have unregistered/registered both instance of msiexec (System32 and SysWOW64). Done this in normal as well as safe mode, rebooting after each try.
- The service is registered and running. (Doesn't stop when it starts.)
- As far as I can tell, registry entries in the MSIServer key are correct.
- When logging the installer results, it reporst an error 1719 right after the line "Connected to service for CA interface"
- Installed service pack 1 but that didn't fix the problem
- Tried every solution found in kb and forums all over the place and nothing does the trick.

This was merely an annoyance at first but now I really need to install and uninstall some stuff and I'm stuck. I don't want to do a fresh install either.

I finally found a solution to my problem.

Altough my MSIServer registry key was correct, there was an Enum subkey that was causing all my problems. Once I removed this key, the 64-bit installer started working again.

Hope this helps anyone with the same problem.

Hello,

I have the same problem and I cant get it fixed.. what is the Enum subkey? and how can I get rid of it

Click Start, type Regedit.exe and press ENTER.

Navigate to the following branch:

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\MSIServer

From the File menu, choose Export, and save the branch to a .REG file.

Exit the Registry Editor.

Open the .REG file using Notepad.

Copy the file contents and post it here.

Hi DAB,

I'm unable to download the attachment (from the Gateway you posted from). Perhaps you can use a newsreader to attach files, or post in plain-text format, or mail the file to me directly.

Hello Ramesh,

I have the same problem. To fix the Enum subkey, you asked Mustafa to
open the .Reg file, copy it and post it to this forum. But, for unknown
reasons he didn't post it. Therefore, I'll post mine instead so that you
could explain how to delete the subkey.

Thanks before hand.

The startup type of Windows Installer was already in Manuel mode. So,
the solution hasn't helped me fix the error.

Salim,

Download and run msiserver.reg linked in that page, even though Windows Installer service is listed correctly. That ought to help.
