copying files to HOMEPATH

hey there,

i've got to install a java development package including some ant targets.
These ant targets have to be installed at %HOMEPATH%/.ant/lib.

my function looks that way

        ReadRegStr $R1 HKCU "Volatile Environment" "HOMEPATH" 

    IfErrors 0 lbl_environment_geholt

        Push "1"    

        Goto lbl_copyAntTasks_ende

    



;   lbl_environment_geholt:

;        ; Ant-Homeverzeichnis prüfen und ggf. erstellen

;        IfFileExists $R1\.ant\lib lbl_antlib_exists

;            CreateDirectory $R1\.ant\lib



    lbl_antlib_exists:

        ; Ant-Tasks kopieren    

        SetOutPath $R1; C:\temp

        File /r d:\install_jade\ant\*.*

;        Exec '"COPY c:\temp\.ant %HOMEPATH%"'

        Push "0"

This function should be able to copy my files but it doesn't! I always get a write error while testing the install file.

As you can see, I tried to copy by a shell copy, too but this didn't work at all. A copy "by hand" works, HOMEPATH doesn't seem to be write protected.

Is it possible to set/unset a writ protection via nsis?

what am I doing wrong?

%HOMEPATH% doesn't have drive specified in it. So you should use %HOMEDRIVE%%HOMEPATH% to get the full path.

Also I recommend that you use ReadEnvStr instruction instead of ReadRegStr to get the environment variables. Not that there's nothing wrong in the ReadRegStr method, but ReadEnvStr uses the proper APIs to get the environment variable.

Copy is an internal command built into CMD.exe and Command.com. Exec needs an actual file. That's probably why EXEC doesn't work for you. You could call it by saying 
ReadEnvStr $0 COMSPEC

ReadEnvStr $1 HOMEPATH

ExecWait '"$0" /c copy c:\temp\.ant "$1"'

well, after solving some problems (concatenating two strings) I got it 🙂
