To install the AKB (Typing Cum Converter) software, just double click on the AKB_Typing_ProV1 file and following everything positively.
After installation you will see the icon on your desktop.
To use it to type Assamese you can select your language and keyboard (Assamese Inscript/Assamese phonetic etc.)

If you check the checkBox (next to Help button) in the toolbar you will see a predictive word list while typing goes on. But this feature doesn't work properly in some machines (typed word's first character remains . So we suggest to use the normal phonetic (box unchecked) if your machine doesn't support this feature.

If your machine supports this feature, then also we suggest to select a word if it appears in the predictive word list, rather than typing the full word.

How to use the converter.

Click on the question mark in the toolbar. You will see Converter. Click on it. Then select your Source Encoding, then paste the text. Press the arrow button.
If you are converting text from Unicode to Geetanjali font, then you have to paste the converted text (you will see them as junk characters, but don't worry) in Pagemaker (so you need Pagemaker installed in your PC).

What is Auto Font and Perfect Conversion?
When you select Auto Font the converted (pasted in Pagemaker) text will show the numbers (both Assamese/English), English characters, symbols, etc. as it was in the source text. But this option has some minor flaws. In pasting process some conjuncts get distorted (ম্ব, ন্ধু, স্ব, ক্স). But when you have mixed text (Assamese, English, numbers) this is much helpful. You just need to check those conjuncts. If you find a such flawed word, copy the same from the original source and convert it using the other option (Perfect Conversion) and paste it again. Solved.
When you select Perfect Conversion, after pasting the converted text in Pagemaker, you have to change the fonts maually to Geetanjalilight if it is Assamese text and to Geetanjalip/Geetanjaliplight if it is Assamese number, and any English font if it is English.
When you mostly have Assamese text (not a mixture of numbers and English), then this is much helpful, it doesn't have conjuncts issue.
