Virtual Directory Creation Fails on Server 2008 RTM

[grahamm]

Hi,

we have an installation that creates a new IIS Application pool during the install. We are finding that on Server 2008 RTM the installation is failing and rolling back due to not being able to find the new application pool. However, on Sever 2008 RC2 the installation is succeeding. I've pasted the failure details from the log below. Has anyone encountered this issue and is there a solution?

Thanks in advance,

Graham


InstallShield 10:00:46: No element found with property 'name' value of 'CustomAppPool'.
InstallShield 10:00:46: Failed to locate application pool. Assuming change in bitness is not safe.
InstallShield 10:00:46: SetAspversion: machine is 64-bit and IIS running in a bit mode other than the currently selected mode
InstallShield 10:00:46: Error with IISRT: -2172

Note that application pools are always installed before any other IIS resources since they may be required, such as in this case. The only reason I can think of causing the app pool to not be installed is the component containing it is not being installed. What is the action state in the log for the component that contains this app pool?

Hi Josh,

the log contains the following entry:

Component: AppPoolComponent; Installed: Absent; Request: Null; Action: Null

presumably this means that the component will not be installed?

Cheers,

Graham

This log information indicates the component will not be installed, nor was it requested to be installed. The next thing to check would be the feature that contains this components. What is the action state of the feature? If it is Null, are there any conditions on the feature or was the feature deselected at runtime?

Hi Josh,

yeah you're spot on. The AppPoolComponent was under the wrong feature, one tied to installing a database, which was being deselected in this particular install.

Thanks for your help on this,

Graham
