64 bit service loaded from Program Files (x86), 32 bit or 64 bit?

I have a service running on a 2003 64 bit server that loads from the Program Files (x86) folder. This folder is where 32 bit programs are usually loaded. In task manager the service shows up as XXXXXservice.exe with out the *32 following.

Is it running 32 or 64 bit and if it is running 32 bit if I uninstall and reinstall in Program Files will it run as 64 bit?

Hi jimmylew52,

if the EXE isn't marked as *32 it sure is a 64-bit process. It makes no difference in which folder the file is located on the harddisk, generally it's of course possible to put 32 bit programs in 'C:\Program Files\ and 64 bit programs in 'C:\Program Files (x86)'.

Any idea why when I run

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319>aspnet_regiis -i -enable

I get this?

The error indicates that IIS is in 64 bit mode, while this application is a 32 b
it application and thus not compatible.

As best I can tell IIS is running in 64 bit mode and the application files will support both 32 and 64 bit modes.

I guess you use the wrong aspnet_regiis which is 32 bit in C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319 - try to start the same from C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319

Hope this helps,
