I was wondering if there is a way to update Windows Vista via a Vb .Net application.
I wanted to use Vista's WUSA.EXE, but it seems that it is only able to do specific updates in a specific location, not all updates.
Info on WUSA.EXE: [URL]

But Application.DoEvents() function halt and crash in windows vista.

I am trying to build a self-updating .NET application that will run in an environment with limited user accounts. No admin rights here. The application must run on Vista and XP, and probably Win 7 when it comes out.An X-copy deployment would be fine. I would prefer NOT to use click-once.So far I have tried a system where the application checks a manifest and downloads updated binaries, which worked great in development, but not so much when the app was installed.Vista refuses to to let me copy files to Program Files. After that, I tried downloading an updated .msi, which works except that the MSI has a UAC prompt -- no go if the user does not have an account with local admin privileges.
running the program in AppData and using the x-copy method might work, but I have not seen anyone say that they have tried it and it did work. Will that work for an account without admin rights? Can anyone vouch for this method before I start writing more code?
I have recently developed an aplication in XP that it works on XP nice but in vista or seven don't work at all. It gives a message when I try to enter the application like " The program cannot run.."

I am trying to create a update application for Windows CE.
It will go out on the net to my site and see if there is any new updates but I am having a problem doing that.

I know there are many posts about updating an application with UAC turned on. We have a huge application and our own update program for updating that. We don't want to use the UserAppData area to install our exes. We do mostly custom programming so updates are a part of like for us. My question is: If we get our update program digitally signed can the standard user with UAC turned on accept those changes without administrator privileges and can that be done to a VB6 executable.
View 8 RepliesWhat are the best practices to develop a software in such a way that I can release updates, I mean I can release an update which replace the existing executable but in case I have added some new references (dlls) to the project this won't work ? Is there any way I can do it without running an MSI?

View 2 Repliesi have created some shareware applications. I implemented the following mechanism for piracy protection. Before Windows Vista and Windows 7 i did write a dll file to the System32 folder with an encrypted license key. Also in the Registry under HKEY_LOCAL_MACHINE i inserted a registry key.
The problem is that with Windows Vista and Windows 7 due to the User Account Control (UAC) this is denied.
I want to ask : what other mechanism can be implemented ? Where should i store the encrypted key file and the registry key.
I want that the application can be installed for all users of a computer only once.
If i stored the key in the user's application data directory then another user could easily just install it under another user account. Also i do not want to put the key file in the application directory because that would be too obvious.
note that i create the registry key with my application and not with the installer.
