Mirror Drive Not Activated

Postby RedAero » 2019-02-11 09:35


As some others, i am also having difficulty getting the mirror driver to activate.

I'm using Win 7 x64 as the server (service mode), Win 10 x64 as the viewer, both UVNC
Server has 3 screens, all 32 bit color depth.
Mirror driver 1.00.22 vistax64 installed separately as admin on server (ran the .bat file as admin). Driver date is 04-11 so seems to eb the correct version. Rebooted twice.

Driver check message is the usual:
Driver found.
Driver version OK
Driver Not Activated, is the viewer current connected ?
A mirrior driver can only be started if winvnc is a service or running as admin.

The server log says:
Code: Select all
vncclient.cpp : Leaving InitAuthenticate

Thanks in advance for your herp.

The mirror driver is limited in memory usage, it's kernel memory.
The kernel memory allocation function often refuse when you want to allocate big chunks of memory.
Try with a smaller display to check if this is the case.
