Troubleshooting Duet client install errors

When attempting to install the Duet client to user in an automated fashion, the install may fail with an error.  The error may seem cryptic, but we have a document on TechNet that can help explain what piece may have failed.  For instance here is a excerpt from a setup log that failed:

 

9/24/2009 : 8:47:28 AM : I:    Invoking Duet 1.5 SP3 Install
9/24/2009 : 8:47:28 AM : I:    Executing following command
C:\Duet\setup.exe ACCEPT_EULA=YES REBOOT=ReallySuppress READSERVICE_URL=https://contoso.com:8020/DuetReadService.asmx /l*v c:\duet_SetupLog.log /qb!-
9/24/2009 : 8:50:47 AM : I:    Unknown Error. Result = 2. Please Check Installer Log for more information
9/24/2009 : 8:50:47 AM : E:    InstallDuet    Duet Installation Failed - error code: 2
9/24/2009 : 8:50:47 AM : E:    InstallDuet    Duet Client Install validation failed
9/24/2009 : 8:50:47 AM : E:    install    Installation/verification failure, see detailed errors

 

If you navigate to http://technet.microsoft.com/en-us/library/cc983797.aspx you will see the following chart:

 

<snip>

/InstallPreReq (or any other install options) – Returns 0 on Success, non-zero values specify the stage at which installation failed.

  • UNSUPPORTED64BIT -1000

  • OFFICENOTINSTALLED 1

  • SQLINSTALLFAILURE 2

  • VSTOINSTALLFAILURE 4

  • DOTNETINSTALLFAILURE 8

  • OWC11INSTALLFAILURE 160

</snip>

 

From this you can see that error 2 indicates that there was a problem with the SQL client installation.  With this information, you can look at other setup logs to figure out why the SQL client failed to install.
