Hello,
During installation of NPM 11.5.3, this issue occurs. Please help me.
"Setup is missing an installation prerequisite Microsoft SQL server 2008 System CLR Type"
download and install both of these on your Solarwinds server.
CLR Types
x86: http://go.microsoft.com/fwlink/?LinkID=239643&clcid=0x409
x64: http://go.microsoft.com/fwlink/?LinkID=239644&clcid=0x409
Then try the NPM installer again.
