SDK Update History
There are many software using the QHYCCD SDK to connect QHY Camera. When the SDK updated, the software maybe not get updated. You can download this file and copy it to the software folder and replace the old more to get your software has the lastest features of QHYCCD.

Update Method
You can update the qhyccd.dll by replacing the original qhyccd.dll in the application software folder.
SharpCAP
You can replace the 32bit qhyccd.dll in the sharcap folder.
EZCAP_QT
You can replace the 32bit qhyccd.dll in EZCAP_QT folder.
ASCOM
Since the old ascom camera driver installation put the QHYCCD.DLL to the windows/SysWow64 or windows/system32. And the recently ascom camera driver put the QHYCCD.DLL into the programe(x86)/common/ascom/camera.  We recommand to delete the QHYCCD in windows/SysWow64 or windows/system32 and put the new QHYCCD.DLL to the programe(x86)/common/ascom/camera folder.
FireCapture
You can replace the 64bit qhyccd.dll in FireCapture 64bit folder  or 32bit qhyccd.dll in FireCapture 32bit folder.
Genika
Only 64bit Genika is under maintain and support QHYCCD. You can find the Genika in Programme and find the 64bit Genika folder.And replace the qhyccd.dll with the 64bit qhyccd_x64.dll (delete qhyccd.dll, rename the qhyccd_x64.dll to qhyccd.dll)
