"Installation or uninstallation is not working temporarily" error when trying to launch Tizen watch application from Tizen SDK - eclipse

Question

When trying to launch the native watch application from Tizen IDE, I see the strange message "Certain application categories, such as "Watch Application", cannot be launched by "Run As".
Indeed, I try to use Run As from the project local menu to launch my app. But how else I am supposed to launch my application on the emulator?
The emulator device (watch) is up and running, visible on desktop as a separate widget. It is selected. The signing configuration is set up.
On the console output I see the message processing result : FATAL_ERROR [61].
I also tried to launch through the created launch configuration but this results the same error message.
The IDE logs show the following stack trace:
[2015.09.06 12:16:48][ERROR] ConnectionExplorer.java(658) - Fail to get platform log
[2015.09.06 12:18:59][ERROR] RdsDeployer.java(269) - Cannot partially upload or reinstall

P.S. I add "eclipse" tag because Tizen SDK is very clearly Eclipse based IDE. Using Tizen IDE 2.3.1.

Watch face applications(Web/native) are never installed as widgets. You cannot see them in app menu.
Reason:
Within your tizen-manifest.xml file in your project, you'll find below line there
<watch-application appid="org.tizen.watchsample" exec="watchsample" ambient-support="true">
which makes your app as watch application and these apps are known as watch faces because they will be used in setting as the main watch in gear.
And on emulator, you cannot change the watch face on the home screen. Hence, you won't be able to test your watch application that way.

Had the same issue. My problem was certificate setup.
i followed there instructions: http://127.0.0.1:50224/help/topic/org.tizen.addon.certificate/html/dev_env/setting_author_certificate.htm
(link is from help and should work in browser when Tizen IDE is up, alternately you can go to Tizen IDE -> Help -> Help Content and search Certificate.
More specific: Distributor certificate i had was wrong (use the pass received by Samsung by email)
After fixing certificate, don't forget to right click your device in Connection Explorer and click Permit to install applications.
