Failed to load XML from package file due to error 0xC00CE556 "Invalid at the top level of the document. Line 652, Column 93". This happens when loading a package and the file cannot be opened or loaded correctly into an XML document. This can be the result of either providing an incorrect file name to the LoadPackage method or the XML file specified having an incorrect format.
This happens when I try to add existing package to opened project. The package was working fine yesterday, nothing has changed. The only thing is that files are copied from one machine to another. Why does this happen? Second time or so... Is there any way or utilty that can check dtsx XML file for errors?
