CAPI Authentication Issues - New Installer

[Rixxan]

The cAPI on the new installer in a small subset of users may have issues authenticating with the cAPI. This often can be identified in logs by a failed attempt to authenticate and lock the journal file, as seen here:

Current belief has this as an issue with the windows registry and protocol handling of the edmc://auth link and how FDEV hands us back the information.

[Rixxan]

As a temporary solution, we may wish to put harder protocol registers in for authenticating using the EDMC:// protocol.

Longer-term solutions might include retiring that handler in favor of localhost default.

I've been able to reliably recreate this occurrence and have some fixes in testing. Longer term solutions may need to be tested further.

As per a 5.8.1 install, you should have registry keys under Computer\HKEY_CLASSES_ROOT\edmc\ to enable the edmc:// handler.

https://github.com/EDCD/EDMarketConnector/blob/develop/resources/EDMC_Installer_Config_template.txt#L71-L80 appears to be missing the ddeexec key as per https://github.com/EDCD/EDMarketConnector/blob/Release/5.8.1/wix/template.wxs#L104-L106 .

IIRC, the ddeexec method is preferred over the shell\open one, so it being missing might be the culprit here.

Agreed with your diagnosis, came to that conclusion yesterday before work. PR opened for fix, is in testing right now. Aiming for fix release on Wednesday? Will see what tests show.

[Rixxan]

Should be fixed. Will leave this open for 3 days for any follow-up issues before closing.
