Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I am having some serious issues with Windows Server 2012 (64 bit) and Coldfusion 10.

I managed to install Coldfusion 10 fine, but cannot open the administrator page or the web config tool.

I am currently getting the error HTTP Error 500.21 - Internal Server Error - Handler "AboMapperCustom-1304376500" has a bad module "ManagedPipelineHandler" in its module list.

ASP.Net 4.5 is installed + added as a role within the server manager.

Any help would be appreciated as this is driving me insane!

Thanks in advance

I believe you can safely modify your application pool by changing the .NET Framework Version to No Managed Code if your web sites do not require .NET –  Miguel-F Jan 28 '13 at 15:50
Hi, I appreciate your response.I have done this and still receiving the same error. Other possible solutions say that you need to run the command: C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i You cannot run this command on Windows Server 2012: This option is not supported on this version of the operating system. –  Ben Thomas Jan 28 '13 at 16:01
Yep I found references to that as well. Didn't realize you cannot run it on Windows 2012. Is that your version of .NET? Are you able to run the .NET framework repair? See the answer to the post here. I assume you could not get CF9 to work as it appears you are now trying CF10. Sorry you're having all of these issues. –  Miguel-F Jan 28 '13 at 17:07
Yeah although IIS says it's version 4.5 the actual folder says 4.0.30319. A tad confusing. I did come across this solution but this doesn't resemble my folder structure as I do not have \SetupCache\Client\setup.exe in there at all. Possibly because it's a server version? I doesn't seem to hidden. Yeah the majority I researched mention CF10 so I thought that might be simpler to get working! –  Ben Thomas Jan 28 '13 at 17:16
