copyfile failed on plateform vista !!

[ChristopheOce]

Hi,

I have a basic msi project who install some file and it's work well.

But on plateform vista i have an error with a function of installscript (CopyFile)

Here is it the code of the function :

 //Copy file
   	nRetCopy =  CopyFile(szPathFile, INSTALLDIR+"\\"+LicenseName);
  	    
    //If != 0 there is an error of copy file
    if (nRetCopy != 0) then

        switch (nRetCopy) 
        case 0: 
            MessageBox ("Files successfully copied.", INFORMATION); 
        case COPY_ERR_CREATEDIR: 
            MessageBox ("A target directory could not be created.", SEVERE); 
        case COPY_ERR_MEMORY: 
            MessageBox ("Insufficient memory.", SEVERE); 
        case COPY_ERR_NODISKSPACE: 
            MessageBox ("Insufficint disk space.", SEVERE); 
        case COPY_ERR_OPENINPUT: 
            MessageBox ("Unable to open the input files", SEVERE); 
        case COPY_ERR_OPENOUTPUT: 
            MessageBox ("Unable to copy the source files.", SEVERE); 
        case COPY_ERR_TARGETREADONLY: 
            MessageBox ("A target file already exists and cannot be overwritten.", SEVERE); 
        default: 
            MessageBox ("An unspecified error occurred.", SEVERE); 
    endswitch; 
          
   endif;
end; 

A custom action type installscript call this function with these parameters :

return processing : asynchronous (wait for exit code)
in script excecution : deferred execution
install exec sequence : after installinitialize
condition : NOT Installed

When the program run the message is an unspecified error occured !
I choose the file with a browse dialog from the c:\ drive and i must to copy it on INSTALLDIR property !

That's works perfectly on win xp, win 2003 but on vista that s failed !

Is there someting to do for execute CA on vista !?
Thanks for your idea !

You might try passing the error code from CopyFile to the FormatMessage function to get a system error message, which might have more information.

A couple of things to check: Does INSTALLDIR have the correct value at that point? Does the action work if you change the action to "Deferred in System Context"?

(And a general tip: in InstallScript, the ^ operator acts like the + operator, but adds backslashes between the pieces if there isn't already a backslash. You can then replace:

INSTALLDIR + "\\" + filename

with:

INSTALLDIR ^ filename

and get a bit of protection from existing trailing backslashes...)

P.S. To avoid a custom action, you might see if the MSI MoveFile or DuplicateFile table (visible in the Direct Editor view) will do what you want...
