How to install SQL Server 2008 R2 Profiler SQL Server Management Studio doesn't have it on the Tools menu in my case, as is reported in some blogs and forums. Apparently you somehow either got it or not, but how did you get it, if you did, is a luck of the draw, or something? I am a MSDN Subscriber.

Is is possible to install the Profiler using some well-defined steps? Like download X, press menu item Y and click button Z sort of prescription? 

[Edit additional info]
Upgrading from SQL Server 2005 Enterprise Edition to Server 2008 R2 Enterprise Edition didn't help (previously, of 2008 R2 editions I had only Express Edition). I am trying Setup program's various options but am unable to upgrade from Basic Tools (originally installed with 2008 R2 Express Edition) to Complete Tools, which I hope would contain the Profiler. Complete Tools option can't be checked in any variation of Setup options that I am trying.
if you allready have a setup of MS SQL Server 2008 R2, try to uninstall the tools only:

setup.exe /ACTION=UNINSTALL /FEATURES=TOOLS /QUIETSIMPLE


And the install it again:

setup.exe /ACTION=INSTALL /FEATURES=TOOLS /QUIETSIMPLE /IAcceptSQLServerLicenseTerms
