Related to
Setting Environment Variables by KiCHiK

There are two ways that i know to change the environment variables

The First Way
You can use the system.dll plugin and in the code call to de SetEnvironmentVariable on the windows kernel
The Second Way
Use a custom plugin, that do this, and this is that i made. :)

Examples

You must change PATH to %PATH%;C:\MYAPP

The Fist Way
ReadEnvStr $R0 "PATH"
StrCpy $R0 "$R0;C:\MYAPP"
System::Call 'Kernel32::SetEnvironmentVariableA(t, t) i(PATH, $R0).r0'
The Second Way
ReadEnvStr $R0 "PATH"
StrCpy $R0 "$R0;C:\MYAPP"
SetEnv::SetEnvVar "PATH" $R0

NOTE: If i do a plugin is because the first way do not run properly with my scripts... maybe i am doing something wrong. :?

Setting Environment Variables por user:kichik:KiCHiK

Hay dos maneras que yo sepa para cambiar las variables de entorno

La Primera
Puedes usar el plugin system.dll y llamar a la funci�n 'call' para llamar a la funci�n del nucleo de Windows (kernel32) 'SetEnvironmentVariable'
La Segunda
Usar un plugin personalizado, que haga esto. Y esto es lo que yo he hecho. :)

Ejemplos

Tienes que cambiar PATH a %PATH%;C:\MYAPP

La Primera Manera
ReadEnvStr $R0 "PATH"
StrCpy $R0 "$R0;C:\MYAPP"
System::Call 'Kernel32::SetEnvironmentVariableA(t, t) i(PATH, $R0).r0'
La Segunda Manera
ReadEnvStr $R0 "PATH"
StrCpy $R0 "$R0;C:\MYAPP"
SetEnv::SetEnvVar "PATH" $R0

NOTA: Si he hecho el plugin es porque la primera manera no funciona correctamente con mis scripts.... quiz� este haciendo algo mal. :?
