ReadEnvStr problem

Hi!

I'm using ReadEnvStr to get the environement variable PATH (local user).

The problem is that ReadEnvStr seems to double the PATH (if PATH is C:\WinNT;C:\toto, i get C:\WinNT;C:toto;C:\WinNT;C:\toto)

ReadEnvStr $R0 PATH

MessageBox MB_OK "PATH : $R0"

How can I make it work ?

EDIT : in fact ReadEnvStr add the system environement variable PATH to the current user environement variable PATH ! Is it something I miss to make ReadEnvStr only get the current user environement variable ?

Try ExpandEnvStrings

ReadEnvStr $R0 PATH works find for me.
This is the value of PATH for me:
C:\usr\bin\;C:\Perl\bin\;C:\WINDOWS\SYSTEM32;C:\WINDOWS;C:\WINDOWS\SYSTEM32\WBEM;C:\PROGRAM FILES\ATI TECHNOLOGIES\ATI CONTROL PANEL;C:\Program Files\Panda Software\Panda Antivirus Titanium\;C:\Program Files\Panda Software\Panda Titanium Antivirus 2004\;C:\Program Files\Common Files\Autodesk Shared\;C:\Program Files\ATI Technologies\ATI.ACE\;C:\BITWARE\;;C:\PROGRA~1\COMMON~1\AUTODE~1

No repetitions...

Here is the part of code

ReadEnvStr $R2 PATH

  ${WriteEnvStr} $R7 "PATH" "$R1\fgl\bin;$R1\mysql\bin;$R2"

And the values I get :

BEFORE INSTALL :
PATH --> LOCAL USER
C:\Program Files\CVS\CVS\Tcl\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\Program Files\UltraEdit;C:\Program Files\Informix\Client-SDK\bin
PATH --> SYSTEM
C:\Program Files\CVS\CVS\Tcl\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\Program Files\UltraEdit;C:\Program Files\Informix\Client-SDK\bin

AFTER INSTALL :
PATH --> LOCAL USER
C:\PROGRA~1\FourJs\gep\fgl\bin;C:\PROGRA~1\FourJs\gep\mysql\bin;C:\Program Files\FourJs\gep 1.00.1c\mysql\bin;C:\Program Files\FourJs\gep 1.00.1c\fgl\bin;C:\Program Files\CVS\CVS\Tcl\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\Program Files\UltraEdit;C:\Program Files\Informix\Client-SDK\bin;C:\Program Files\FourJs\gep 1.00.1c\mysql\bin;C:\Program Files\FourJs\gep 1.00.1c\fgl\bin;C:\Program Files\CVS\CVS\Tcl\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\Program Files\UltraEdit;C:\Program Files\Informix\Client-SDK\bin
PATH --> SYSTEM
C:\Program Files\CVS\CVS\Tcl\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\Program Files\UltraEdit;C:\Program Files\Informix\Client-SDK\bin

It doubles everything.

I've find a way to escape this but i'm not sure it's clean but it works :

ReadRegStr $R2 HKCU "Environment" PATH

  ${WriteEnvStr} $R7 "PATH" "$R1\fgl\bin;$R1\mysql\bin;$R2"

There is a special piece of code for handling the PATH variable. Use that instead of WriteEnvStr.

Thx kichik, i'll try that.
