The error dialog that appears has the title Setup Initialization Error and an error string that looks something like the following:
Setup cannot access the required initialization file 'C:\PROGRA~1\SAP\FRONTEND\SAPGUI\FILC\ODBC\AUNCHER="C:\DOCUME~1\USERNAME\LOCALS~1\TEMP\"'.
There is a compatibility issue that prevents Visual Studio setup from being able to copy itself to the %temp% directory and relaunch itself if the SAP GUI client application is installed on the computer. The telltale indication that you've hit this problem is the \SAP\FRONTEND\SAPGUI\ information in the path listed in the error dialog during VS setup.
Solution：
renaming the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\<b>setup.exe</b> to something else e.g. <b>sapgui_filc_odbc_setup.exe</b>.
