KBHere’s a new Knowledge Base article we published this morning that talks about an issue you might run into when trying to install the Microsoft Application Virtualization client using the MSI instead of setup.exe.  Fortunately it’s an easy one to resolve:



When running the Microsoft Application Virtualization 4.6 Desktop Client (App-V 4.6) by running SETUP.MSI, you may receive the following error:

Error 25010. A prerequisite for installation is missing.
Installation cannot continue.

This error can occur if the proper versions of the Microsoft Visual C++ 2005 and 2008 redistributables are not present. Setup requires the following redistributables:

  • VC++ 2005 Redistributable version 8.0.59193
  • VC++ 2008 Redistributable version 9.0.30729.4148

Running SETUP.EXE rather than SETUP.MSI will automatically extract and install these packages. See How to Install the App-V Client by Using Setup.exe (http://technet.microsoft.com/en-us/library/ee956911.aspx) for more information.


Running setup via SETUP.EXE is the preferred method to install the App-V client. To install the client using only MSIs use the following steps:

  1. Install the Microsoft Visual C++ 2005 SP1 Redistributable Package (x86) (http://go.microsoft.com/fwlink/?LinkId=119961)
  2. Install the Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL Security Update (http://go.microsoft.com/fwlink/?LinkId=169360)
  3. Install the Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) (http://go.microsoft.com/fwlink/?LinkId=150700)
  4. Install the App-V Client using SETUP.MSI

Note that KB2467174 and KB2467175 should be applied to update these packages as well.

More Information

The App-V client setup requires VC++ 2005 Redistributable version 8.0.59193 and VC++ 2008 Redistributable version 9.0.30729.4148 before setup will proceed. These packages need to be installed in addition to KBs 2467174 and 2467175 to satisfy the requirements of the Side-by-Side manifest. The order of installation of the packages does not matter.
