If you remove an App-V package from the connection group, the state that existed as part of the connection group will not migrate with the package. If the same package is a part of two different connection groups, you have to indicate which connection group App-V should use. For example, you might have two packages in a connection group that each define the same registry DWORD value. The connection group that is used is based on the order in which a package appears inside the **AppConnectionGroup** XML document: -- The first package has the highest precedence. - -- The second package has the second highest precedence. +- The first package has the highest precedence. +- The second package has the second highest precedence. Consider the following example section: -``` syntax +```XML ``` -Assume that same DWORD value ABC (HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region) is defined in the first and third package, such as: +Assume that same DWORD value ABC (HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region) is defined in the first and third package. -- Package 1 (A8731008-4523-4713-83A4-CD1363907160): HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=5 +For this example, the DWORD value definition would be the following: -- Package 3 (04220DCA-EE77-42BE-A9F5-96FD8E8593F2): HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=10 +- Package 1 (A8731008-4523-4713-83A4-CD1363907160): HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=5 +- Package 3 (04220DCA-EE77-42BE-A9F5-96FD8E8593F2): HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=10 Since Package 1 appears first, the AppConnectionGroup's virtual environment will have the single DWORD value of 5 (HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=5). This means that the virtual applications in Package 1, Package 2, and Package 3 will all see the value 5 when they query for HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region. -Other virtual environment resources are resolved similarly, but the usual case is that the collisions occur in the registry. +Other virtual environment resources are resolved in a similar way, but usually collisions occur in the registry. -## Merging identical package paths into one virtual directory in connection groups +## Merging identical package paths into one virtual directory in connection groups +If two or more packages in a connection group contain identical directory paths, the paths are merged into a single virtual directory inside the connection group's virtual environment.
