Depois de algum tempo tendo as menssagens irritantes do Windows Installer consegui remove-las.

Uma instalação com problemas após a remoção das versões beta do Microsoft Web Expression, fez com que cada vez que usa-se algo no Windows XP Pro, como Office, Visual Studio, Internet Explorer, Outlook Express etc, desse uma mensagem do tipo Windows Installer .... não pode instalar etc.

Bem achei a solução após pesquisar e nada encontrar muito positivamente.

Faça o seguinte:

Crie uma cópia do registro;

Baixe o software Windows Installer CleanUp Utility do link

http://www.softpedia.com/get/Security/Secure-cleaning/Windows-Installer-CleanUp-Utility.shtml

A seguir acesse a pagina http://en.wikipedia.org/wiki/Windows_Installer

E então crie o novo valor no registro conforme descrito no artigo da wikipedia:

"

• Windows Registry: The following registry value can be used to enable verbose logging:

Key: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer

Value Name: Logging

Type: REG_SZ

Data: voicewarmup

"

A seguir abra a pagina temp colocando no campo de endereço do meu computador o texto %temp%

Voce vai ver aquivos com nomes parecidos com MSI3170b.LOG ou MSI*****.log

Abra os arquivos, voce pode faze-lo com um editor como o Textpad.

Verifique as mensages do tipo:

....

MSI (s) (1C:6C) [00:29:53:743]: SOURCEMGMT: Attempting to use LastUsedSource from source list.
MSI (s) (1C:6C) [00:29:53:743]: SOURCEMGMT: Trying source x:\VISIO_FOR_ENTERPRISE_ARCHITECTS\.
....

MSI (s) (1C:6C) [00:30:25:028]: MainEngineThread is returning 1635
Este pacote de patch não pôde ser aberto. Verifique se o pacote de patch existe e se você pode acessá-lo ou entre em contato com o fornecedor do aplicativo para verificar se este é um pacote de patch válido do Windows Installer.
x:\VISIO_FOR_ENTERPRISE_ARCHITECTS\VISVEA.MSI
MSI (c) (14:40) [00:30:25:038]: Decrementing counter to disable shutdown. If counter >= 0, shutdown will be denied. Counter after decrement: -1
MSI (c) (14:40) [00:30:25:038]: MainEngineThread is returning 1635
....

Observe que neste caso meu problema era que toda vez que rodava um programa como Internet Explorer, Outlook Express ou Office, o Windows Installer procurava instalar novamente o Visio for Enterprise Architects.

Uma vez verificado as mensagens de log, foi só remover a entrada utilizando o Windows Installer CleanUP e Pronto. Sumiram as indesejáveis mensagens.

Quase que reinstalei todo o sistema mas não foi preciso.

Portanto ai vai esta dica e espero que seja útil a você.
