I have a similar problem. So I tried to start Speccy with debug according to the instructions above. But I get an error msg when I use the command line. I use "C:\Program Files\Speccy\Speccy.exe /debug". I get the following error msg:
"Windows cannot find 'C:\Program Files\Speccy\Speccy.exe /debug'. Make sure you typed the name correctly, then try again. To search for a file, click the Start button, then click Search.'
Now, I can start Speccy with the Run command line without the '/debug'. It would seem that Speccy is not recognizing the variable being passed to the program.
I needed to start '/debug' because every time I start Speccy it hangs after about 15-20 seconds, then my computer reboots. I have no problem with CCleaner & Defraggler.
I have uninstalled & re-installed Speccy several times already.
Any ideas?
