What does the error say? There should be a hint about what went wrong. If not, try to set CustomErrors=Off in web.config to get the errormessage to display.

One guess would be that the permissions are not set correctly so the packages can't be installed?

I usually let the app pool have permissions set through a .bat script that I run in the website root:

icacls app_code /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)RX
icacls app_browsers /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)RX
icacls app_data /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
REM icacls bin /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)R
icacls bin /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls config /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls css /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls data /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls masterpages /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls macroscripts /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls media /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls python /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls scripts /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls umbraco /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls usercontrols /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls xslt /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls web.config /grant "IIS APPPOOL\yourapppoolhere":(OI)(CI)M
icacls web.config /grant "IIS APPPOOL\yourapppoolhere":M

Sometimes its nessesary to have the "Network Service" also have these rights, I think that may have to do with the trust-level.

If you want to try, just copy my script into a new txt and save it with the .bat extension. (Change yourapppoolhere with the name of your app pool).

Hope that solves it :)

Thanks Niels, but we're talking umbraco as a service here :)

Theres no access to IIS or App pools.

Aaaah, my bad... Didn't see that.

Hmm.. Interesting though :)

Claus -

Does the YSOD have a stck trace?  If so, can you provide it?  The UaaS base site is designed to allow package installs...so wondering if there's more information there that will point up the root cause.

Hi Claus -

I think your instance may be missing the createdPackages.config file in \app_data\packages\created\

If you'll add one via the site's Git repo I think package installation will work as intended.

Best, -Paul

Well, another problem has come in to play :) I cant access the site right now. Getting a 502

is working on a reply...
