[FIXED 3.1.5181] V. 5180: no "ZWO" section at top of Camera menu

I'm using SharpCap v. 3.1.5180. I have a Win10Pro 64 bit laptop, and am using a ZWO 1600MC-Cool camera, with latest ZWO drivers.

The "ZWO" section near the top of the Camera menu is missing. DirectShow is the first listing instead. I just reverted back to v. 5174 and the "ZWO" Camera section appears correctly near the top of the Camera menu.

Hi,

3.1.5180 has a new ZWO SDK in it - I wonder if that perhaps requires you to update your ZWO drivers to the latest version to work? What camera are you using that is not showing up? I think I tested with the 071MC and it worked...

cheers,

Robin

Hi Robin,

I'm using a 2nd-generation 1600MC-C. I've been using this camera with SharpCap for a while, and this is the first time I've had this issue. All my ASI drivers (native, ASCOM, DirectShow) are the latest versions, downloaded back on May 4 from ZWO's website. I did not have this issue in v. 5174.

I've attached the log files from my attempts in v. 5180 to open this camera where there was no "ZWO" section listed under the Camera menu. Thanks for looking into this issue.

Hi,

there is nothing bad in the log files, but also no sign of SharpCap detecting the ZWO camera properly. I will test my 1600 (MM) later. I noticed when I was looking at ZWO drivers today that they updated their drivers on the date you mentioned (4th May), so it would be interesting to know if you ended up with the very latest (3.0.0.4) or the previous one (3.0.0.3).

cheers,

Robin

Ok, I understand the problem now - it's to do with upgrades - if you upgrade from a previous version to 5180 then the ZWO camera dll goes missing. If you do a clean install of 5180 (ie uninstall older version of 3.1 first) then it's fine.

I know the cause too - ZWO did an odd thing and changed the version number of their DLL so it reduced and that doesn't work nicely with certain install/upgrade scenarios. The odd thing is that I *thought* the way I was doing things wasn't going to have that problem - sigh...

Working on a fix, but do a clean install as a workaround for now.

cheers,

Robin

Ok,

first, thanks for reporting this - it's let me find and fix a silly and very annoying issue.
second - the fix is now available by

* installing 3.1.5181

you can also work around the problem by

* uninstalling and then reinstalling 3.1.5180
or
* going to the control panel and repairing 3.1.5180

third... I still don't understand quite why it happens - all the documentation I can find seems to suggest that what I was doing was correct and it should have worked without a problem, but it clearly didnt :( Oh well, that's life sometimes!

cheers,

Robin
