Execute .reg file?

Moritz Gutwein

Dear friends,

i'd like to execute a reg file from the desktop. With this file, i write some informations to the registry. I know, i can write directly to the registry with:

key.SetValue("Example");

But afterwards, if i want to change some informations, i always need to change to whole program. So i tried:

Process regeditProcess = Process.Start("regedit.exe", @" /S /r C:\Users\example\Desktop\oeminfo.reg");

It starts correctly and asks for permission but when i accepted, nothing happens to the registry. I think there is some problem with the 64 bit Version, because there was the same issue with the RegistryKey method.

Sorry for potential mistakes.

lg Moritz

Too bad, nothing happend. Do you know another way to execute this reg file? And I saw that there could be a problme with 64 bit version?!?
Because when I write to the registry via key.SetValue, it looks like this:

using (var hklm = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))

You see the ending? "Registry64"? Maybe its because of this...
I just dont know how to use it

No problem, I am convinced there is a solution for it! I will try the restart and tell you if it worked!

I'm sorry my friend that my code didn't help you!

I assume you're logged in as Administrator, but you can try to restart machine. Maybe it helps, but I'm not confident enough.

Hi Sumit Jolly,

I tried your code snippet. But I get the same result as before. And I dont think it is because of the missing administrator permission. Because I already wrote:

to the app.manifest. And I am not sure if I missed something, but there is sadly no pop-up dialog. Could it be, that it only shows the change after a restart?

it seems you're missing administrator permission, you may want to try something below:

ProcessStartInfo info = new ProcessStartInfo("regedit.exe", @" /S /r C:\Users\example\Desktop\oeminfo.reg");
info.Verb = "runas";
Process.Start(info);

this might pop-up dialog box asking for username/pwd to run this. if you're admin over the machine then it should ideally work?

please try and let me know if this helped you or not.

Sorry for my bad expression. This problem happens when i start it within the application. Like there is a kind of permission missing.

If there are any questions about it, just ask!
Btw. thanks for your help!

Yes it starts as when i double klick it on the desktop. In the next step i have to confirm to write right into the registry. The next window shows "Succesfully writen to registry". But when i refresh the registry, nothing has changed...

Sorry, one last question when you double click the application or you double click on .reg file above behavior happens?

if you fire this command
regedit.exe /S /r C:\Users\example\Desktop\oeminfo.reg

does it fire perfectly, I mean does it update registry file?
