I upload vnc on my server and when i execute it : winvnc.exe -install i get this error :
The vnc service could not be installed
what am i going to do ?
Which operating system? I assume Windows because of the file name, but it would be helpful to state it; also, which version of Windows?
And, BTW, what VNC are you using? There are quite a lot of them around.
Being Windows, a standard question is: do you have Administrator rights on that server?
Also, are you trying to install it on the server's physical console, or using a Remote Desktop connection? Some versions of VNC just don't let you install them over RDP.
Your problem sounds like it could be caused by the file being blocked by windowns.
Now attempt to install again.
