It seems the online creator UltraVncSC update 2011 suddenly replaced SCHook.dll from v1.0.0.1 to 1.0.0.2.
Was it ever officially announced? It's funny that a 2011 package contains 2012 materials.
After more 2 000 000 (two million) views on forum for 1.5.0.x development versions... and 1.6.1.0, 1.6.3.0-dev versions
A new stable version, UltraVNC 1.6.4.0 and UltraVNC SC 1.6.4.0 have been released: https://forum.uvnc.com/viewtopic.php?t=38095

Re: UltraVncSC update 2011 suddenly changed SCHook.dll
If bugs are found i also update the online compiler.
schook is the same for winvnc full and sc.
schook was missing some hints ( schook give hints about the changed screen locations)

Re: UltraVncSC update 2011 suddenly changed SCHook.dll
Not exactly. SCHook.dll from the regular uVNC is 65,784 bytes, while the SC version is 72,440 bytes.
Why is that?
In any case, if v1.0.0.2 fixes bugs, it should have been announced. Otherwise most SC admins out there wouldn't know they can upgrade their SC packages.

Re: UltraVncSC update 2011 suddenly changed SCHook.dll
Then i need to check.
SC is a seperate source tree build on a old XP with VC6.0 ( very old compiler).
It could be that i needed to make changes on the schook source to make it build on VC6.0.
Anyway, all SChook versions are compatible you can always use another version.

Thanks for the fix (it's now called "Update 2013")!
