Installing daemon program

[egsuh]

I'm trying to try a daemon program. I followed wiki and example on following page. My project files are attached.

https://gitlab.com/freepascal.org/lazarus/lazarus/-/tree/main/examples/TDaemon

But I got the following error(the quoted content is copy of command window). What am I doing wrong? As I'm a beginner to daemon area, I cannot point my error.

D:\Programs\Daemon>testdaemon -install

Did you check if you have space on your disk?
Or maybe you need admin rights?

I'm really sorry. I should have run the command window as administrator
