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 ?
Your problem sounds like it could be caused by the file being blocked by windowns.
Now attempt to install again.
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.
