.NET Forum / .NET Framework / New Users / August 2005Determining the path to the .NET framework
Is there a canonical way to determine the path to the folder where the runtime environment is installed? The reason I am asking is that I have created a small Office Add-In in C# which needs to be registered as a COM component using regasm.exe during installation. So I need a way for the install script (the Add-In is only a part of a larger project which does not use the default Microsoft installer) to find the regasm, since it is not in the path by default.

Unfortunately that won't work in the scripting language of the setup utility, unless I can write a small .NET executable to call during the installation process which returns the result of the call to me. I was hoping there was a way to get this value from the registry, for example. I don't know of an officially documented one, but HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework has a value named InstallRoot that gives you the framework's root directory (without the version number). Usually this value is "C:\WINDOWS\Microsoft.NET\Framework\" This seems to be consistent with v1.1 and v2.0, however, you still need the version dependent part of the path. On my v2.0 VPC, there is a subkey with the v2 version number, however this is not consistent with v1.1. HTH Free MagazinesGet these publications absolutely FREE for up to 12 months.
