Using Windows Server 2008 R2 and SQL Server 2005 SSRS, trying to install Dynamics AX 2009 reports.
Installed the client and reporting extensions fine and connected to the AOS server. Running the Microsoft Dynamics AX Reporting Project Deployment setup and it was failing with:-
The following components have not been installed or are not configured correctly:
AL.exe
Microsoft Domain-Specific Language Tools

Fix:-
Looks like you need to download and install 2 files:-
Windows SDK for Windows Server 2008 and .NET Framework 3.5
&
Microsoft Visual Studio 2008 Shell (isolated mode) Redistributable Package
Run both these setups and run the Microsoft Dynamics AX Reporting Project Deployment again and you now might get the following error:-
The following components have not been installed or are not configured correctly:
Microsoft Domain-Specific Language Tools

Seems like when you run the Microsoft Visual Studio 2008 Shell (isolated mode) Redistributable Package it just un-compresses the actual setup file on the Hard Drive in my case under:-
C:\VS 2008 Shell Redist\Isolated Mode
Run the following file found in the directory:-
vs_shell_isolated.enu.exe
And then re-try the Microsoft Dynamics AX Reporting Project Deployment again and all should be well - phew!
