when I try to start my tcserver instance I get the following:

-> tcruntime-ctl.bat insight-instance install
INFO Running Windows architecture: winx86_64

sight-instance
wrapper | OpenSCManager failed - Access is denied. (0x5)

I've googled and found this error in a number of places (with various suggestiuons), but not for tcserver

I'm running Win7-64bit with Springsource 2.6.1 Release

Can anyone here help me?
