Hi,

How is it handled when I do not check for admin rights and users install 
my program without admin privileges?

In this case, they won't be able to register the program in the global 
Uninstall list/MSI registry I guess.

However, what happens when program with same UpgradeCode is first 
installed globally as administrator and the next version installed as 
non-admin user?

I especially ask because at first my application needed to register a 
COM object and therefore required admin privs:

     <Condition Message="Administrator privileged required">
       Privileged
     </Condition>
     <Property Id="ALLUSERS">1</Property>
     <Property Id="WIXUI_INSTALLDIR" Value="INSTALLDIR" />

Furthermore I wrote a DLL which searches old instances from my 
application (using a proprietary Installer) and removes it first. This 
also required admin privileges.

However, the new version does not require admin privileged any more (COM 
object does not need to be registered).

What is the correct way to handle this situation?

Regards
Luke
