Solution to failure to access the Windows Installer Service

Recently, when installing the software, a dialog box will pop up after loading the software: unable to access the Windows Installer Service..., resulting in installation failure.

Later, I found that the COM component on my machine had a problem with loading, and the phenomenon was:

1. Start-run-dcomcnfg and go to the component service management page. Component Service-computer-my computer, COM + applicationProgram

And DCOM configuration display is not normal, click DCOM configuration directory, the management page is automatically closed. Depressing...

2. Check the event log and find the following error:

The runtime environment detects inconsistency in its internal status. This indicates that there is potential instability in the process, probably because of

This is caused by running custom components, components used by COM + applications, or other factors.

3. Google has found such a solution. E. The reasons and implementation steps are briefly described here.

Cause: COM + catalog is destroyed

Solution: (not applicable to Windows Vista, Windows Server 2008, Windows Server 2008 R2, and Windows 7)

3.1 rename % WINDIR % \ system32 \ clbcatq. DLL to % WINDIR % \ system32 \~ Clbcatq. dll

3.2 stop COM + Event System Service and set its Startup type to non-automatic

3.3 restart your computer and enter the Registry (Regedit)

3.4 Delete the Registry: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ com3

3.5 command line: cd % WINDIR %, rmdir/s registration

3.5 control panel-add and delete programs-add and delete Windows Components and reinstall them directly next

Over.

Supplement: If IIS has been installed (it will install several COM + components), the above process will cause it to lose these components.

Run rundll32 % WINDIR % \ system32 \ inetsrv \ wamreg. dll and createiispackage to create the package.

NOTE: If rename/delete operations are blocked during the above process, you can perform this operation in security mode.

At this point, the COM + error is resolved, but the Windows Installer cannot access the error. Continue.

4. There are many Google websites. Here we only record the ones I use.

4.1 rewrite the registry, use NotePad to edit the following content, save it as a. reg file, and double-click it to complete the import.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ msiserver]

"ImagePath" =-

"ImagePath" = hex (2): 25, 00, 53,00, 79,00, 00, 00, 6d, 00, 6f, 00, 6f, 00 ,\

, 00, 5C, 79, 00, 00, 00, 6d, 00, 00, 5C, 00, 6d ,\

, 00, 2f, 00 ,\

4.2 In security mode, type msiexec/regserver.
