uninstall product + deletedir

[ChristopheOce]

Hi,

I have a basic msi project who installs some dll dotnet, xml file and so on !
When the product is remove, some file (.exe, .txt, shortcut, ..) are always prensent on the INSTALLDIR at the end of uninstallation !!!

For to try to solve this problem, i've add a installscript function :

....
 if (ExistsDir (szPathInstall) = EXISTS) then
        
        nRetDel = DeleteDir(szPathInstall, ALLCONTENTS);
        if (nRetDel = 0)then
             MessageBox("all was deleted", INFORMATION);
        else 
             
             NumToStr( val, nRetDel );
             MessageBox("UNABLE TO DELETE FILE" + val, SEVERE);
            
        endif;  
        

This custom action is well executed in the sequence before installfinalize with REMOVE="ALL" as condition.

Of course, when i uninstall my product the messagebox appears and contains -1 as the returns value !!!!

If i try to place the format message(nRetDel), the result is empty !

hm hm rather boring :-), someone have some idea for how to find why my file is not remove while the uninstalling sequence and how i can solve this problem ?

Thanks for your idea
Christophe

My project is an Installscript MSI, so I'm not sure if this will help or not...

But in my code, I have:

DeleteDir ( INSTALLDIR , ALLCONTENTS );

I don't capture a return value for the DeleteDir function or display any message and it seems to work fine. Also as you can see I use the variable INSTALLDIR which is automatically populated with the installation path. I think some of the other project types use TARGETDIR instead.

Hi nmsams,

Thanks for you reply, but my variable szPathInstall is INSTALLDIR 🙂

nRetDel = DeleteDir(szPathInstall, ALLCONTENTS);

And i don't know why when i remove the product some file (shortcut, xml, dll, exe) are always present on the target machine !!!!

It s not everytime, i have a machine xp and it's arrives everytime and on my build machine win 2003 it never arrives !!!!

I'd like to understand why it's arrives and why i can do for to solve this problem..

If you have any idea, don't hesitate 🙂

Thanks for all
Christophe
