On some systems, when you install the latest version of Xpress over the top of the old version of Xpress (upgrade rather than remove) when it says it is complete the old version is still loaded.
To prevent this, first use Windows Add/Remove programs to remove the existing version. (This does not reemove projects, just the Xpress Software)
After the old version is removed, install the new version. In some cases it may be necessary to reset the local project path to see your existing applications. If your local projects window does not show your projects after the upgrade don't panic. The default directory changed in order for new versions to comply with Windows 7 file rules for where you can save project data.
The old directory was:
C:\Program Files\Parker\Interact Xpress Manager\Projects
The new default is:
C:\Documents and Settings\"your username"\My Documents\Parker Hannifin\Interact Xpress Manager\Projects
This path can be changed in the Xpress Manager under "Settings" at the top left corner of the window.
