How to find Regasm.exe and use it in a .Bat file

I need to use RegAsm.exe to register several assemblies in a .bat file; however, since RegAsm.exe is not in the system path, it is difficult to just use like Regsvr32 which is always in the system path.

You can use the WINDIR enviroment variable to get the root of the path. It will probably be something like:


You then need to add "\Microsft.NET\Framework\" to the path, and finally the path to the specific .NET Framework you are using:

SET fwpath="%windir%\Microsoft.NET\Framework\v2.0.50727"

%fwpath%\regasm.exe app.dll

Error 1001. Exception occurred while initializing the Installation:System.IO.FileNotFoundException

I found this info from the following post:


I later found the Microsoft documentation on solving the problem:
