Try compiling your service specifically for 64 bit systems:

-Right click your service project in the solution explorer
-Choose Properties
-Select the "Build" tab
-Set the "Platform Target" dropdown to "x64"
-Recompile your service, recreate the installer and try installing it again

Please note: When the service is compiled this way, it will not run on 32 bit systems, so you need to compile and deploy two different versions.

Also: If your 64 bit service makes use of 3rd party dll's that are compiled for 32 bit systems, it will throw an exception when it tries to load the dll's

Good luck,
Johnny J.

Solution 2

There are two options:

Use corflags to set 32 bit capability:
corflags assemblyname /32Bit+

Compile the application as Any CPU.
