Environment Variable used by nsExec:ExecToLog

Hi,

I have a problem, which is caused by calling an external program using nsExec:ExecToLog.
I managed to gain some infos that the environment variable (in this case the %PATH%) used by the nsExec:ExecToLog is not correct.

I found that there is registry entries for the env. var.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\"

During in the installation process, which update the env variable, the values in the registry and the values displayed by calling

ReadEnvStr $0 PATH

are different.

I've checked by displaying the values in the registry on the log and they are different. My external program update the %PATH% env variable in the registry and also displayed correctly.

My question:
1. Which env. variable %PATH% is used by nsExec:ExecToLog?
2. Is there any other windows registry values, which are relevant to this env. var. settings??

Thank you very very much for the help.

The installer, and therefore nsExec as well, uses the environment of its parent process. If that's Explorer, it's the most up-to-date value. If not, it depends on what happened first, the lunch of the parent application or the value change.

HKCU\Environment holds the user's environment and also affects it.
