All versions of GX up to, and including V4.5z, were developed using an
old version of the Microsoft Dev System.

We were obliged by Microsoft, as part of our Partner status, to upgrade
to a 'modern' version of MSDEV.

GX V4.6, and later, are developed using Visual Studio 2010.
The program used to compress GX.EXE to GXnnn.EX_   
(and GXIO.EXE to GXIOnnn.EX_) was a very old 16-bit DOS utility. It    
doesn't work with Windows-7 so when we retired our last Windows XP     
machine we had a problem. Unfortunately, the compression algorithm of  
the 16-bit program doesn't seem to be supported by any modern compression  
utility so we decided to switch to one of the standard ZIP algorithms.  

The V4.6a version of the GX is unique. It itself is compressed, as       
GX46a.EX_, by the old algorithm, but it includes the new expansion       
algorithm for V4.6b and beyond. So if you attempt to go directly from   
V4.5 to V4.7c, say, the expansion will fail because V4.5 will expect the
gx46f.ex_ to be compressed using the old way, but it will actually be   
compressed using the new algorithm. 

However by using the files below, you can go from an older version of GX (via 4.6a) to
4.6f without it failing.


GLOBAL.EXE 5.1d
P.$SDLM0  (needs to replace existing one on SYSRES)
$STARX (needs to be copied into P.$CMLB1 on SYSRES)

Or make sure that you are running GSMSP-33 or later with GLOBAL.EXE 5.1d or later.


Ensure that:

02/09/2015  10:33         2,054,806 GX46a.ex_
27/10/2016  09:19         1,585,463 GX47c.EX_

are in the "gxupdates" folder.

When you run say GX 4.4z, it will upgrade to 4.6a, then restart GX & upgrade to 4.7c.

So, say you are all up to date, eg running GSMSP-33 or later, global.exe 5.1d or later, GX 4.6a or later & are supplied a 4.7 GX file in the form of GX47.EX_ What do you do with it? Simply copy it into the gxupdates folder on the Global Server (eg c:\gsm\gxupdates), invoke your GX session, it will update to 4.7 & restart GX, so long as your registry looks something like:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Global\Client\ServicePacks]
"UpdateGXFiles"="on"
"GXUpdateDirectory"="C:\\gsm\\gxupdates\\"
"PromptForGXINIUpdate"="On"
