I have installed visual studio 2010 and it is working properly.
In my machine their is 2 GB RAM and i3 processor what else need to be installed for Rho studio
but i am still getting error filed to create java virtual machine.
Visual Studio has nothing to do with RhoStudio, though, except that is is used for certain parts of the build process. (Compiling C/C++/assembly code).
2GB RAM is pretty small these days for any kind of software development. You need to load Eclipse (RhoStudio is just a pre-configured Eclipse environment), which is a memory hog, and, as well, Visual Studio. If you decrease memory allocations in Eclipse, you are likely to just run into even more trouble, rather than solving it.
I would recommend upgrading to 4GB if not 8.
Thanks Hector, your solution works.
