hehe! I thought there would be interest.
It's a huge pain when it's running on a machine that doesn't have internet access like an old laptop off-site at another location.
If you delete the entire directory and re-install it still won't run.
Basically they leave some hidden stuff in the registry.
When it's uninstalled that stuff is still there. Even if the registry info is deleted it still won't run because when the petrol runs out they stealthily dirty some of the files so it won't run without a new petrol file regardless.
I couldn't be bothered to figure out what files exactly are modified since a delete and re-install via batch file takes just a few seconds.
See attached .bat and .reg (zipped)
Run the .bat it will delete the files then run the .reg and kill the registry stuff. If you put cncsetup453.exe in the same dir it'll re-install it for you. The tool files remain untouched.
.bat file contents....
del "C:\Program Files\CncSimulator\*.*" /q
cnc_uninstall.reg
cncsetup453.exe
.reg file contents....
Windows Registry Editor Version 5.00
[-HKEY_LOCAL_MACHINE\SOFTWARE\ChMts]
"msCheck"=dword:00000002
The minus before HKEY removes the entry. You can double-click the .reg to remove it manually.
Note that once this gets out they will probably change it and release a new version (typical cat and mouse game software companies play with hackers) so get the current version 4.53f now and keep it handy
The file is cncsetup453.exe , 3.92 MB (4,114,451 bytes)
Looks like they are working on a pro version now. Something I look forward to cracking in the future. Or maybe they will come to their senses and realize that CNC machines don't run on petrol. Hmmmm.
Enjoy
