QHY5LII Driver---Camera doesn't install into ASCOM Chooser on some Windows 7 and Windows Vista pc's of Maxim DL Pro users:
Note: this is **NOT** a problem with Maxim. It appears to be an ASCOM/camera driver problem. Cross-posting here since some who like me use Maxim DL Pro might encounter this error on their pc's with this camera driver.
***Documentation of problem installing latest QHY5LII ASCOM camera driver on some Windows 7 64-bit or Windows Vista 32/64-bit pc's***
This information is provided to assist others who encounter this same problem on their pc's, and to assist the ASCOM developer who works with this camera and its driver files. I'm cross-posting the info here since it affected my use of Maxim DL Pro V.5.23 with this camera until I was able to fix it.
The QHY5LII camera drivers didn't install into the ASCOM/ASCOM Chooser properly on my Windows Vista 32-bit and Windows 7 64-bit pc's.
It **DOES** however install into the ASCOM Chooser properly on a Windows XP 32-bit pc that I tried it on and it does show up OK on the Chooser drop-down list of cameras on the Win XP pc, and will display the camera Properties tab OK on the Win XP machine. But the camera drivers didn't install correctly on my Win 7 64-bit or Win Vista 32-bit pc's.
SYMPTOMS AFTER THE CAMERA DRIVER INSTALLS:
ASCOM "Profile Explorer" tool does not show the camera driver installed or the Chooser Keys installed either, on those two pc's.
You can't choose the QHY camera from other apps such as Maxim DL Pro
because it is not on the Chooser drop-down list of cameras.
The camera drivers and ASCOM camera driver files installed are all the latest ones offered at the QHY download link as of 6/15/2013:
Camera drivers....file name: QHY5_IIDrv64V13-01-06.
ASCOM driver...file name: QHY5LIIASCOMSetupV04.e
My ASCOM on all three pc's is Version 6 SP1, build 6.0.10028.2207
STEPS TAKEN TO INSTALL INTO ASCOM MANUALLY AND FIX:
1) Manually added ASCOM Profile Explorer Keys inside the Profile Explorer window. I copied and pasted the Key header syntax over to the ASCOM Profile Explorer headers from the Profile Explorer Keys on the Windows XP machine where the files DID install correctly.
For those who can't do a copy over of the header syntax, two .jpg screen shots of the Profile Explorer headers can be found here so you can make the Key edits correctly:
In case the longer link below is truncated:
(Sorry, could not get the Files section here on the group to create a folder for this, so I had to put it at my astro website link shown above. Download the .zip file to access the two .jpg screen shot files of the Profile Explorer).
2) ASCOM now accepted the manual Key edits into the Profile Explorer OK (does now show up in the Chooser drop-down list OK), but when attempting to select the camera in the Chooser and look at its Properties, I got an "ASCOM Helper.Chooser" error and the properties would not display.
3) To fix #2 above, I ran the "ASCOM Diagnostics" tool from the "Tools" folder of the ASCOM installation (from the Windows Start Menu/Programs link to ASCOM). The diagnostics tool did find the Chooser Helper error and successfully corrected the registration of the drivers on both the two pc's.
The camera drivers and ASCOM drivers now seem to be working properly on the Win 7 and Win Vista machines.
As always, do this fix at your own risk and make sure you run pc and Windows registry backups first. I have no way of knowing if this fix will work on other pc's, but it did work on my two problem pc's.
