Hi there!

To help you with this we'd like to ask you a few things:

- Are you using UWS.RegApp.exe to register the application or UWS Config API?
- After you get an error, can you open UWS Explorer and save configuration for any existing or new application? Do you get the same error by any chance?

Best regards,
UltiDev Team.

Hi there!

We will re-test this scenario. If there is a race condition, while UWS file is locked and other things like listen endpoint creation is in progress, then you may need to introduce a delay and/or add custom action code to check whether UWS web server config file, "UWS.Configuration.xml", is not locked.

If we can fix it by delaying registration until it can proceed, we'll add it to the next release.

We'll let you know in a few days what we have found.

Best regards,
UltiDev Team.

Sorry, my mistake, the C:\Program Files\... path I quoted was incorrect. I transposed it (badly) from the messagebox that came up. I apologise!

Here is the Event log entry:

Failed to register or unregister application due to
"System.ApplicationException: Failed to save application configuration from "C:\ProgramData\UltiDev\WebServer\UWS.Configuration.xml".

Command line:
"C:\Program Files (x86)\UltiDev\Web Server\UWS.RegApp.exe" /r /AppID={AC93FAEA-0192-4D52-861A-A91F664FA3FB} /aspnet:4 /vdir:WS "/path:C:\Program Files\ACHS\EAT5_NS\\EAT5_NS\WS"

The parameters for Starter.exe I use in the custom action are:

"[ProgramFilesFolder]\UltiDev\Web Server\UWS.RegApp.exe" /r /AppID="{AC93FAEA-0192-4D52-861A-A91F664FA3FB}" /aspnet:4 /vdir:WS /path:"[TARGETDIR]\EAT5_NS\WS"

It seems a bit strange that the Event viewer command line ends up with a double backslash in it, but as stated earlier this application registers perfectly if I run a repair after the initial installation, so this seems unlikely to be a significant issue.

Thanks, I figured I'd probably be able to workaround the problem with some sort of delay. I'll proceed on that basis for now.

Cheers

Hi!

Not a problem at all. Thank you much for bringing this problem to our attention.
