Bueno esta es una pequeña función la cual nos permite obtener información detallada sobre las aplicaciones instaladas utilizando la API del Installer de Window, no es necesario leer ya las entradas del registro para obtener esta información , lo malo es que solo lista las aplicaciones que utiliza el installer , las demás las desecha porque no lo usan. También añadi otro pedazito de code para desinatalar las apliaciones con esa misma API. Bueno saludos y espero que les resulte interesante. Option Explicit

Nada mal pero, lamentablemente mustra unas pocas apps, en mi caso 2 contra ccleaner que tiene 15.
Mira que MsiEnumProducts es vieja, hay una nueva funcion llamada MsiEnumProductsEx pero no es soportada por todas las versiones de MSI obviamente.

Realmente el problema es que hay algunas aplicaciones que no utilizan el Installer para instalarse por lo que al instalars no añaden los registros al installer, entonces el installer solo tiene los registros de los que lo usan, este ejemplo solo funciona con las aplicaciones que el installer ha registrado, hay otra forma enumernndo todas las aplicaciones desde el registro las cuales estan en esta key : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall Dentro de 5 minutos pongo un ejemplo de como listar esas de ahi  Saludos. |
