Inno Setup RegAsm.exe Errors

Question

I am trying to build a 32/64bit installer all in one. The only thing that is different on a 32bit vs. a 64bit machine is a call to RegAsm.exe. For a 64bit machine that code has to look at the 64bit framework and for a 32bit it looks at the standard framework.

32bit: "C:\windows\microsoft.net\framework" 64bit: "C:\windows\microsoft.net\framework64";

I have my package setup to run Install actions. For my 64bit action I have the check enable for IsWin64.

Filename: {dotnet4064}\Regasm.exe; Parameters: """mydll.dll"" /codebase"; WorkingDir: {app}; StatusMsg: "Registering Add-In"; Flags: RunHidden; Check: IsWin64;

Several lines of the log file before the error

This all works fine on a 64bit machine. In a 32bit machine I get an error:

Internal Error: Cannot run files in 64-bit locations on this version of Windows

I've been all over the help documentation and google and cannot lock down a reason as to why this is happening. Any help is appreciated.

I resolved this by adding: ArchitecturesInstallIn64BitMode=x64 and then using Check: Is64BitInstallMode
