Hi,

I have faced the similar error 0x800C0005 once when I was trying to download one of the application update from Microsoft , and I had to research for a whole day to resolve the issue, but resolve I did, and found the actual reason for this error.

Actually this error occurs when some dynamic link library files (.dll) are not properly registered OR the second reason maybe when there is a FIREWALL which prevents HTTPS (SSL) connection.

Now in your case, as you mentioned that you also tried to run the full setup which failed, which means that the .dll files are NOT correctly registered. To resolve this issue, follow these steps:

·         Click on start – run – and type cmd, press enter

·         On the open command prompt type( without qoutation)  “regsvr32 Softpub.dll” press enter

·         Now type “regsvr32 Wintrust.dll”  press enter

·         Now type “regsvr32 Initpki.dll”  press enter

·         Press OK

This procedure will reregister several .dll file.

Restart your computer.

Your issue will be resolved now.

I thought you are already installing Microsoft .NET Framework 4.0 when the error “0x800C0005” appears. Because you are still in the process of downloading the .NET installer, the cause of the problem is probably your web browser. Another possible reason for this is when you are using the web installer for Microsoft .NET Framework 4.0.

You will get this error code together with a “download failure” message. The previous post is correct. This happens if there are specific DLL files that are not properly registered or you are using a firewall software that blocks HTTPS connection. If you are using a third-party firewall such as Comodo Firewall, try to deactivate it first and then restart the download.

Another way of going around the issue because it mostly happens if you use the web installer is to download the standalone or offline installer of Microsoft .NET Framework 4.0. To download an offline installer, visit Microsoft .NET Framework 4.0 Standalone Installer. It supports Windows XP Service Pack 3, Windows Vista Service Pack 1 and up, and Windows 7 both x86 and x64.

For servers, it supports Windows Server 2003 Service Pack 2, Windows Server 2008, and Windows Server 2008 R2.
