Outlook 2007 installs every time I open it



I recently purchased Office 2007 Small Enterprise. Installation for all the
components, but Outlook went fine and they are all functional. Outlook
however, will not install properly. Each time I open it, it reinstalls.
I've uninstalled and reinstalled using the various options (install on
machine, install only when needed, etc) after doing registry cleaning and
nothing works.

Another problem is that the Office Live Connector, which I had set up in
Outlook 2003 does not recognize that I have Outlook installed at all.
Thinking the Connector might be the problem, I uninstalled it too and then
reinstalled, to no avail. Any suggestions? Thank you in advance!

Anybody who has resolved the issues with the other office progs, but is still having it with Outlook then here's the solution I found....

Event ID 1004, event ID 1001, and event ID 1000
To resolve the issues that are related to event ID 1004, to event ID 1001, and to event ID 1000, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

Note You can perform this procedure on a Terminal Server console or on the local computer, depending on the location on which the Office program is installed

Start a Terminal Server client session, and then log on as a user.

Note If you have installed the Office product on the local computer, go to step 2.
Click Start, click Run, type regedit in the Open box, and then click OK.
In the left pane, locate and then click the following registry subkey:

On the Edit menu, click Permissions.
In the permissions for Installer dialog box, click Administrators in the Group or user names list, and then make sure that the Full Control permission is set for the Administrators group. If this permission is not set, click to select the Full Control check box under Allow.
Click OK.
Repeat steps 5 through 6 for the SYSTEM group.
Repeat steps 5 through 6 for the Everyone group. Verify that only the Read permission is set for the Everyone group. If this permission is not set, click to select the Read check box under Allow.
Repeat steps 4 through 8 for the following registry subkeys:
Clear the Application log, start the Office program, and then see whether you receive the event IDs that are mentioned in the “Symptoms” section.

If you still receive event ID 1004, delete the UsrClass.dat and UsrClass.dat.log files for every user on the terminal server or on the local computer. To do this, follow these steps:

Click Start, point to Programs, point to Accessories, and then click Windows Explorer.
In the left pane, locate and then click the following folder:
Drive:\Documents and Settings\USERNAME\Local Settings\Application Data\Microsoft\Windows
NoteDrive represents the drive letter for the hard disk drive partition on which Windows is installed.

This Windows folder is in a hidden folder. To view the Windows folder, you must configure the folder settings to display hidden files and folders. If you cannot locate the Windows folder, verify that the folder settings on the computer are configured to display hidden files and folders. To do this, follow these steps:
On the Tools menu, click Folder Options.
In the Folder Options dialog box, click the View tab.
Under Hidden files and folders, click Show hidden files and folders, and then click OK.
Verify that the Windows folder is now available.
In the right pane, right-click UsrClass.dat, and then click Delete.
Click Yes when you are prompted to confirm the file deletion.
Repeat steps 3 and 4 for the UsrClass.dat.log file.
Start the Office program, and then verify that the event IDs that are mentioned in the "Symptoms" section are not logged in Application log.
