Windows registry - need to give permissions

Currently got an issue at work where I need to setup 3 different users permissions to be the same, for arguments sake let's call them Bob, Jean & Julie.

There's an application installed on the PC which stores data in the registry under a specific software name under "hkey_current_user\software\developer name\application"... unless the user has full control permissions to this route, they have to enter the configuration details everytime they logon to the PC, as it loses the detail when they log off.

Bob & Jean's settings work fine, however for Julie it keeps on dropping the setting.

I have tried setting the registry permissions with full control as 'everyone', as well as for their specific domain\username. I have also tried setting them as local administrators on the PC.

When Julie logs on, if I do Win+R and enter regedit, it says this has been blocked by an administrator and doesn't allow to access. This is really the first hurdle, as if you can help me get them access to the registry then I should be able to work out the rest from here.

I was expecting this to be more straightforward than it has been so far... from a frustrated IT Techy.

Thanks

yes it works as local administrator, but not for Julie who is a standard user that I've added in to the local administrators group on the PC.

just tried with Julie's login on another PC and it works fine... so I get a feeling the registry is corrupt somewhere from all the changes attempted.

the PC has been reimaged a couple of times but has made no difference, it stores the data fine for two of the users in the hkey_current_user area of the registry but for the third user it doesn't store any of the data.

am i right in thinking therefore all it should take is for the particular key to be set for read & write access for this third user for it to work?

The software is installed locally, and it needs set configuration settings which are stored in hkey_current_user\software.... but if the user doesn't have permissions to this folder, it loses the settings each time they log off and back on again. Does that help?

ok, I did export the reg keys and added to the startup folder for this user that needs them, however, I found that each time they logon rather than it just importing or asking if they want to import, it comes up with the message access denied to the registry... or something along these lines.

again... it doesn't quite make sense that it works for some users but not others, when they all have same permissions.
