Hi Bhavesh,
I couldn't locate the attachment in your post. I guess 'BW Modeling tools' was not installed correctly on your computer. This is the sequence to follow.
1. SAP HANA Studio
2. ABAP Development Tools
3. BW Modeling tools
Please refer note "1954169 - BWMT - Installation details" for a step by step guidance.
Regards,
