I wrote a guide to install it and I uploaded the patch and the drivers here, including how to solve the connection trouble on the Windows XP SP3 computer (Error #434: The requested baud is invalid) This is because you need to patch ET 2011A.
I know that anything isn’t going to work like the original, but at this time is the tool I have in my hands.
For those like me, I upload the files and I put the links on the attach bellow:

Here a leave the instructions:
* Clean install
* Install ET 2011A
* Install FTDI USB to UART Driver
* Install CP210X USB to UART Driver
* Open the ET 2011A. Click “Utilities†> “License Cat ET†> Generate code and paste it.
* If your OS is Windows XP goto step 7 or Windows 7/8 goto step 8.
* Copy “CommunicationAdapterServer.exe†to “Program FilesCommon FilesOffboard Information Productsâ€
* ONLY IF WINDOWS 7/8. Open Cat ET 2011A Patch. Select unit and os guest (32 or 64 bits). And click Patch, it would show you Patched it message OK.
* Reboot computer.
* Connect USB and bluetooth and wait to install and disconnect them.
* Go to properties on “My computerâ€, open hardware management and check USB and bluetooth com port number.
* Open the ET 2011A and goto Utilities->Preferences->Communications
Select “[URL=https://www.obd2tool.com/category-39-b0-Heavy Duty Diagnostic Tools.html]Heavy Duty Truck diagnostic Scanner[/URL] Caterpillar Comm Adapter II (Dual Data Link/Serial lP)
Select the same COM port as you noticed in step 11 (USB or bluetooth the one you already connected. 1 only)
It works now. I tested it on a Cat 950G and it show me the 3 ECM, however I’m having trouble to connect with a Cat 416E, I get the message check cable connection, no cable detected.
But it works perfect on a Cat 950G.
Regards.
