I've developed a tool that makes updates in many mxd files. When it runs in my machine, everything works fine, and I can open the mxd and see the updates made by the tool. When the tool runs in any other machine, the updates are made, but when open the mxd to see the updates, they can't be seen. When I open in my machine, I can see the updates. Both machines has the same ArcMap configurations, ans service packs. Any Ideas?
