Re: [Demexp-dev] Re: win32 and GTK

[GISQUET Christophe]

Good evening,

I've updated the installer with the latest change, i.e. embedded GTK installer 
+ detection:
http://christophe.gisquet.free.fr/demexp/demexp-0.7beta-2.exe

Of interest are difficult scenarios where:
- the user has (very) limited rights
- no GTK installation exists
- an installation exists, possibly installed by someone (root) with higher 
rights.

I believe this is still somewhat unstable so some tests are required.

I have attached a patch that expects the GTK+ installer to be named 
"gtk2-runtime-2.8.18-setup-1.exe" and present in the win32 folder. Most 
modifiable strings are available at the beginning of demexp.nsi. In addition, 
but this is not included nor demonstrated, even the installer can have custom 
translations.

I'm detecting and displaying the GTK version. GTK is not installed if a 
version is already installed. Note: this detection is somewhat unsufficient, a 
broken installer/desinstallation or some other unusual situation may trick it.

I leave that work to the integrated gtk installer which is included. It is 
extracted to the TEMP folder ("Docs & Settings\<Users>\Temp" or the like) and 
run from it. This occurs as the very step of the installation. If the GTK 
installer is canceled/..., demexp installation fails.

Former solution implemented.

only first verification implemented.

Done. GTK check box can't be modified; I don't think the case where people 
want to force the installation of the demexp version is worth the modifications.

Done.
