The above script gives the ouput of the HPOV ( HP Openview )Version

I need to add a if statement to check if HPOV installed,If installed it need to run the script else need to say ÖV not installed on the Server in HTML format

i.e.I need to check if OvInstallDir is there in the server if so then need to run the script else come out of the script saying "OV not installed on the server" in the HTML format

OvInstallDir=C:\Program Files\HP\HP BTO Software\

Can you help me on this?

this path " 'C:\Program Files\HP\HP BTO Software\' " may vary for server to server .so actually Path is not necessary.
.just to check OvInstallDir is installed

Check if that path is saved in registry then we can lookup value from it

Suresh KumarAuthor Commented: 2017-03-22
