Title

Product installation failure: .NET framework has to be installed

Problem

When trying to install FileUp, the installation fails with the message that .NET framework must be installed, even though the .NET Framework is in fact installed. The situation can be the same for FileUpEE installation.

Solution

FileUp's installation process performs the following steps:

It attempts to load mscoree.dll into memory
It attempts to connect to the local IIS
If #2 succeeds it attempts to find script mapping for the .aspx extension

The third step is likely where the installation process is failing. It is possible that the aspx script mappings that FileUp installation relies upon do not exist in the metabase if the .NET Framework was previously installed.

To correct:

Add a script mapping for the aspx extension.

Open IIS, right-click the Default Web Site, and select Properties.

Note:

In the Windows XP IIS console, the Web Sites and Default Web Site nodes have identical properties dialogs. The script maps can be installed in the Web Sites properties, but they will be ignored by IIS. The script maps must be installed from the Default Web Site node. Select the Home Directory tab. Click Configuration. Select the App Mappings tab.

Click Add.
Browse to aspnet_isapi.dll (typically in C:\WINNT\Microsoft.NET\Framework\<.NET Build Number>\).
In the Extension field, enter aspx.
Select All Verbs.
Check Script Engine, and click Ok.
