Ejabberd 2.1.11 installation issue: erl.exe: can't execute: (14001) Error 14001

I tried to install ejabberd 2.1.11 and got the next error:

Starting ejabberd...
./ejabberdctl: e:\bin\erl.exe: can't execute: (14001) Error 14001

" There is a problem starting Erlang.If the error you see is 14001, you need to install:
Microsoft Visual C++ 2005 SP1 Redistributable Package
You can download that installer from www.microsoft.com
You can also check the ejabberd Administrator Guide "

I have installed ejabberd 2.1.11 on two machines, one with Windows XP SP2 and one with Windows server 2003 Standard edition. Both with VC++ 2005 SP1.
VC++ 2005 SP1 was already installed before starting the ejabberd installation.

I have manually locate and run erl.exe and in the eventViewer I got (in both machines):

"Generate Activation Context failed for C:\Program Files\ejabberd-2.1.11\bin\erl.exe. Reference error message: The referenced assembly is not installed on your system."

and

"Dependent Assembly Microsoft.VC80.CRT could not be found and Last Error was The referenced assembly is not installed on your system."

Also when running erl.exe a pop-up window appears with the message: "C:\Program Files\ejabberd-2.1.11\bin\erl.exe This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem."
Anyone have a idea why this happening?

Thanks in advance for your time.
