My temporary solution has been to remove the web.config file just to get the thing to install but obviously I need to get this resolved. What does Flexera Software recommend? Follow up: I discovered the issue was that the web.config file was not checked out in Visual Source Safe/Team Foundation Server when creating the installer, which led to the resulting web.config file being in read-only mode. And we know from experience that having the web.config file in read-only mode causes this error. So my fix was as simple as making sure the file was checked out. Anyone else seeing this issue should be aware of this. I had never seen this issue when installing in a Server 2008 environment but it definitely happened in a Server 2012 environment. ... View more

Are you saying that the solution is to have the web.config file checked out at the time the web installer build is being made? That would be an acceptable workaround and is something I will test to see if it resolves my issue. ... View more
