Per-user redirection (ATL DLL) doesn't work?

Hi

I have a problem registering a ATL proxy DLL as per-user. I found a post which says per-user registration would work using the

regsvr32 /n /i:user "xxxx.dll"

command, but this fails (DllInstall entry point not found). I also can't find any useful documentation about DllInstall or the /i:user option.

The DLL exports DllCanUnloadNow, DllGetClassObject, DllRegisterServer and DllUnregisterServer.

regsvr32 "xxxx.dll" works when it is run elevated.
