Midas.dll and COM+ applications deployment issues

It is a known fact that Midas.dll needs to be registered before installing/registering a COM+ ActiveX Library under COM+, when deploying an ActiveX library written with Delphi, right?
Well... something interesting that I discovered this week: DON'T register a Midas.dll version 10.x (from BDS 2006 installation). Use a lower version - I'm using my D6 dll.
If you use version 10.x it will be registered without any errors, but when you try to install the ActiveX Library, boooom!!! You will get a "Error loading type library" error, as Midas.dll was not registered at all.
After ActiveX Library installation/registration, Midas.dll can be even deleted (If you are linking with MidasLib.dcu), as usual.

ASP.NET Compilation Error

Another common error I've found installing ASP.NET web services in IIS:

"Compilation Error - The compiler failed with error code 128"

This error has a simple solution: Just go to your .NET subfolder, for instance,

%SystemRoot%\system32\Microsoft.NET\Framework\

and type

aspnet_regiis -i

This will re-install and configure ASP.NET for IIS.
