Windows 8.1 black screen problem

Post by luka1002 »

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

-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.

When i remove w8hook.dll from destination machine, i have picture but on every click i got connection drop and i have to wait to reconnect. Firewall is ok , can this happen beacuse of this dll?
