Accepted answer

it may be due to this breaking change in eclipse 3.6:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.platform.doc.isv/porting/3.6/incompatibilities.html?view=co#objectcontribution

edit:

looks like it definitely is. see https://bugs.eclipse.org/bugs/show_bug.cgi?id=309074. here's the fix:

in the "customize perspective" dialog, go to the "command groups availability" tab and check "team" and "svn".

in eclipse mars.2 (4.5.2) this is under window->perspective->customize perspective... dialog, "action set availability" tab. (try to restart eclipse if it doesn't work after you change it). customize perspective dialog screenshot

all eclipse workspace settings are stored in <eclipse-workspace-name>\.metadata\.plugins\org.eclipse.core.runtime\.settings folder. so, try copying this folder from your 32bit windows xp environment into 64bit windows 7 setup.
