Crea las carpetas siguientes:
- %System Root%\DOCUME~1
- %System Root%\DOCUME~1\ADMINI~1
- %User Profile%\LOCALS~1
(Nota: %System Root% es la carpeta raíz, normalmente C:\. También es la ubicación del sistema operativo).
. %User Profile% es la carpeta de perfil del usuario activo, que en el caso de Windows 98 y ME suele estar en C:\Windows\Profiles\{nombre de usuario}, en el caso de Windows NT en C:\WINNT\Profiles\{nombre de usuario} y en el caso de Windows 2000, XP y Server 2003 en C:\Documents and Settings\{nombre de usuario}).)Otras modificaciones del sistema

- %Windows%\a.exe
- %Windows%\b.exe
- %Windows%\c.exe
- %Windows%\d.exe
- %Windows%\e.exe
- %User Temp%\C__DOCUME~1_ADMINI~1_LOCALS~1_Temp_QvodSetupPlus.exe.torrent
- %User Temp%\C__DOCUME~1_ADMINI~1_LOCALS~1_Temp_QvodSetupPlus.exe.mem
(Nota: %Windows% es la carpeta de Windows, que suele estar en C:\Windows o C:\WINNT).
. %User Temp% es la carpeta Temp del usuario activo, que en el caso de Windows 2000, XP y Server 2003 suele estar en C:\Documents and Settings\{nombre de usuario}\Local Settings\Temp).)Agrega las siguientes entradas de registro como parte de la rutina de instalación:

Soluzioni
Step 1
Los usuarios de Windows ME y XP, antes de llevar a cabo cualquier exploración, deben comprobar que tienen desactivada la opción Restaurar sistema para permitir la exploración completa del equipo.
Step 2
Eliminar esta clave del Registro
Importante: si modifica el Registro de Windows incorrectamente, podría hacer que el sistema funcione mal de manera irreversible. Lleve a cabo este paso solo si sabe cómo hacerlo o si puede contar con ayuda de su administrador del sistema. De lo contrario, lea este artículo de Microsoft antes de modificar el Registro del equipo.
