Hi Hari,
Please see SAP Note 2226948 - SAP NetWeaver Developer Studio 7.5 - Installation and Update:
***********************************************************************************************************************
Installation steps:
- Download the archive for the Developer Studio from SAP Service Marketplace.
- Open the archive and extract its content in a folder on the file system.
- Open the eclipse folder and start eclipse.exe.
- When the Developer Studio starts it opens a window where you need to enter a location for the Workspace folder. In the Workspace folder, the Developer Studio stores the configuration settings, which you provide and the local projects, which you develop.
***********************************************************************************************************************
So the file is eclipse.exe.
I hope your issue is solved now.
Regards,
Hemanth
