I am recieving it when I try and install the DNN Feedback module from Hosts->Extentions->MoreExtentsions.

First, I searce feedback.
Next, find DotNetNuke Feedback (Minimum Version Required: 06.01.02 )
then, Then Click Deploy DNN Feedback
then Click Deploy.

Once Deploy is clicked I revieve the error.


What I have done so far.

I have added my APPPOOL\{AppPoolName} to the IIS_IUSRS Group.

I have given the IIS_IUSRS Group full controll of every folder in my DNN Installation.

from here I dont know what else to do.

Did you find any answers Martin?

Mine happens when I try to install a module via  --   Hosts->Extensions->MoreExtensions=Deploy.

I added the APPPOOL\{application pool name} user to the IIS_IUSRS Group and granted full control of the root folder of the website to the IIS_IUSERS Group.

Still no resolve.

Martin, have you found out anything more?

I am running DNN on SQL2012, IIS7.5,  Windows 7
