In case Bernhard Hiller describes the problem correctly in his Solution 1, and the problem is Telugu input, I already explained my approach. You can use Microsoft Keyboard Layout Creator.

"Compilation" with this application creates MSIs for different platform and Setup.exe choosing the right one for your computer and doing the installation.
