CommonAppDataRegistry throws a UnauthorizedAccessException'

[EDN Admin]

 Im writing a litle app that <u><b>reads</b></u> some values from the regestry (Installation or admin user has written these values)

When I try to access this, while running the app as a standart user I get the following exception:
System.Windows.Forms.Application.CommonAppDataRegistry threw an exception of type System.UnauthorizedAccessException
Under Admin everything works as expected.


My Test Code

<div style="border-right:#7f9db9 1px solid;border-top:#7f9db9 1px solid;font-size:11px;overflow:auto;border-left:#7f9db9 1px solid;line-height:100%! important;border-bottom:#7f9db9 1px solid;font-family:Courier New;background-color:white

My question is why?

In effect CommonAppDataRegestry points to the exect same location as the test key.

Can anyone advise me what Im doing wrong?
