Hi Frederik,
The Eclipse is located in C:\developmenttools\JDT
What i noticed is with checking the issue with my colleagues, is that the DevTool I used up to this point was named Hana Studio straight away and not Eclipse. I assume by default it had some plugins which are missing from this installed Eclipse version, which are necessary for these perspectives
Since i was the labor rat, only i tried this installer, but missing the hana perspectives are really hurting.
Best Regards,
Mihaly
