Support for Shared Configuration in IIS when creating application pool

[TFAlex]

Hi Forum / Support,

We just had a scenario, where a customer runs two servers with IIS that use shared configuration.

iis-shared-configuration.png (28.24 KiB) Viewed 5226 times

With that active, the installer always stopped the installation process while creating the application pool for our application with an error and would not continue. Alas, I don't have the full logs anymore, just some things I remember. It said something about "com-error" and "access is denied" while "committing to MACHINE/WEBROOT/APPHOST". The Advanced Installer Error Number was 4034.
When the shared configuration was disabled, everything worked fine.
Do you know this problem? Is this a known limitation of advanced installer? Is there some workaround to this?

Thanks for any answer or help
Alex

Hi Forum / Support,

I just managed to reproduce this on one of my local, virtual test servers. These are the settings for the shared configuration, that lead to the failure:

When mapping the share to a local drive letter instead, it would work. Using a network path like in the screenshot, it won't.

These are the last few lines in the log file:

Hi Alex,

I am afraid this is indeed an Advanced Installer limitation. Thank you for bringing it to our attention. We will try to address an improvement in this regard in the future. When such enhancement is available we will update this forum's thread.

However please note there is no ETA we can offer for moment and to be honest most likely this will get a lower priority on our dev team roadmap. Thank you for your understanding.

All the best,
Daniel

Hi Daniel,

thanks for the reply. At least for me it's clear now, that we didn't make a configuration mistake and that it is just not supported. It's interesting that this never came up before because I could've guessed that a lot of bigger companies use shared configurations. On the other hand, how many software providers use advanced installer in their product to configure an IIS server Thanks in advance for an update on the release of this feature / fix somewhen in the future.

Regards,
Alex
