Since week before, we were on Windows 7 X64 and we had no problem. Group policy deployment was used to copy uvnc.ini ,execute mslogin.exe with import and install msi.
Last week we got new computers with Windows 8.1. So i installed latest 1.2.0.5 Uvnc, with new ini file and tested localy. I can login to remote computer, but after that i can not see desktop. It is black, but on source computer i can see movement. We installed addons in uvnc folder but nothing...
Any help?
Regards,
Luka

Re: Windows 8.1 black screen problem
-Try:
*Remove w8hook.dll on a pc that has the black issue and try again.
The hook make use on special functions that exist in the new video drivers.
It could be that it's not supported on the remote pc
*It could be a premission issue, the new hook use shared memory
If server is not stared as service, try with "runas administrator"
vnc use the existing hook ( order: w8hook, schook,vnchook) if the dll exist.
