AaronLST,

1. Please open the "Properties" of RegAsm.exe file in this location. The File version on my machine is 2.0.50727.1433. Except the file version, there is regasm.exe.config file in the same location. Please open the check this XML file on the imageVersion node. You can set this value to v2.0.50727

2. I have also the .NET Framework 1.1 installed with the regasm.exe file version 1.1.4322.573. If you are using Windows Server 2003, there will be .NET Framework 1.1 installed with the operating system.

3. If there is no SP1 for your .NET Framework 2.0, please try to reinstall the framework with SP1 in the link below:

If there is any further issue, please feel free to reply. Thanks again for your question.

I am not concerned with the version of the RegAsm.exe, and there is no need for my users to change the version of the exe. I don't see how manipulating version numbers is at all helpful to locating RegAsm.exe. I asked specifically about the location of the file, not its version.

That is more on target, but my question is only regarding .NET 2.0. My app has a requirement that .NET 2.0 already be installed, therefore I am only concerned with finding RegAsm in the .NET 2.0 installation.

I don't see any reason to require my users to install SP1. My application works fine without it. It is up to them and their administrators to decide when SP1 is an appropriate upgrade. I should not enforce additional requirements upon them that are not necessary.

My question is a simple yes or no question.

Are there versions of .NET 2.0 for which RegAsm.exe is installed to a folder other than "%WINDIR%\Microsoft.NET\Framework\v2.0.50727"?

For example, one response may be:
'Yes, there was a release of .NET 2.0 which installs to "%WINDIR%\Microsoft.NET\Framework\v2.0.12456"'
or
'No, all official releases of .NET 2.0 install to "%WINDIR%\Microsoft.NET\Framework\v2.0.50727"'

Notice the key element of a reponse to a Yes or No question is Yes or No, and often followed by a clarifying restatement of the question. This is one of those things Microsoft doesn't teach you in their .NET Framework Design Guidelines classes, because it falls more in the scope of human language rather than computer languages.

I would simply go out and try to find every version of .NET 2.0 that I can and install each one to a clean VirtualPC, but I would still be left wondering if there are versions that MS no longer provides links to on their website for which some of my users may have.

Sorry, just frustrating that MVPs mark there own responses as answers when they haven't even addressed a question. It's like people don't even read before they respond.

If you are registering from code, You may use Environment.GetRuntimeDirectory() to get the directory where regasm.exe is.

It is a API-call that allows you to find the root of the .NET installation without using managed code.
