Question

During my innosetup application installation, I am registering a dll (which is used for windows right click context menu and icon overlays, something similar to dropbox/tortoise cvs) and performing some other stuffs also. Till now, I am insalling the application only for the administrator user. The dll will write the information in HKCR, HKLM. Now, I plan to support installation for other non-admin users too (standard user).

I tried several things like below,

• changed the privilegerequired from Admin to none.
• changed all registry updates from HKLM to HKCU.

But, if I try to install the application, the dll registration failed due to unable to write on HKCR. So, I planned to register dll only for the admin user. And for other normal users, plan to skip the dll registration and do the other stuff. But I can’t find out, how to identify the current users is a admin user. Can any one let me know the following things,

• can we identify whether the current login user is a admin/power user or not?
• can we register dll (writing HKCR) with out admin rights?

Thanks for your reply.

Answer 1

You can check whether the current user is admin or power user:

[Code]
function IsRegularUser(): Boolean;
begin
    Result := not (IsAdminLoggedOn or IsPowerUserLoggedOn);
end;
