Eclipse updgrade 32 bit to 64 bit windows 7

Question

I am running 32 bit windows with 32 bit Eclipse Luna and 32 bit Java 7 for android development. No issue. Now I am planning to upgrade RAM and install 64 bit Windows 7 . So my question is if I upgrade my Windows 7 from 32 to 64 bit , keeping all program files(which are in C drive) and then download and install 64 bit Eclipse Mars with Java 7/8 64 bit , will my workspace open and work as like now? Or I have to format C drive, install 64 bit Windows 7 and freshly install Android SDK etc ? My workspace is in D drive.

Answer 1

If you want to switch to 64 bit. you need to download eclipse and JAVA for 64 bit. And you can link your existing SDK to the new eclipse in windows tab. as I did the same thing in my PC it's working fine for me

Linking Android SDK to eclipse

in Eclipse --> Window --> Preferences --> Click On Android --> Browse your SDK location --> Click Ok .

Answer 2

It is possible to instal JRE in to Program Files for 64 bit, other JRE in to Program Files(x86) for 32 bit. And then to change the JRE in : Windows > Preference > Java > Installed JRS's > edit or add.
