WyUpdate bug in Windows XP

HelloI am getting this error when trying to update on Windows XP "The following files are in use, these files must be closed before the update can continue "c:\program files\myCompany\mySoftware\escUpdate.exeThe update works fine on later versions of windows .

Any the thoughts on how to fix this issue ?

Are you including wyUpdate.exe (or "escUpdate.exe") as part of your update? If so, don't. Check all the versions in your wyBuild project and remove all instances of "escUpdate.exe".
