NSClient++ and registry keys to allow arguments

Setting up new NSClient++ on WIndows servers, trying to check the status of just one service, ut keep getting the dreaded :

Exception processing request: Request contained arguments (not currently allowed, check the allow arguments option).

SO plenty of people out there with hints for this, but they all involve editing the .ini file - great, except I used the registry method to configure NSClient++. Hmmm. Clint Boessen's blog pointed me in the right direction - set the config key "allow arguments = 1" so I did the closest thing I could think of in the registry, and it worked. Cool:
