component consists of guixt.exe and guixt.dll. When GuiXT is
started by sapgui, it checks that the file versions of guixt.exe and guixt.dll
match, otherwise GuiXT stops and shows the error message
"Different versions of ...", the message that you just got.
In most cases, this occurs if the file guixt.dll is still "in use"
when one installs a new version. We have never seen a situation in which the
sapgui patch contains different versions of the guixt files.
I suggest that you install the most recent GuiXT version, 2006 Q3 1, running the
setup program guixtsetup.exe that is available for download at http://www.synactive.com.
Or you can install a more recent patch of sapgui 6.40 (6.40 patch 20 is now
delivered by SAP) that will also contain a 2006 version of GuiXT.
