Non-Administrator Install With No List on Add/Remove Program

Post by Random_Thoughts »

Well as far as I know without admin rights you have no permission to install any programs....... Part of the restrictions in user name!

Luckly for you I know of a way to go around it:

1. Turn on computer
2. Before Windows Starts (Right after black screen with alot white letters) Press F8 Repeatedly.
3. Use Arrow Keys, Select Safe Mode with Networking press ENTER.
4. At Login screen click Administrator (If a password is set you will need a program that bypasses the password)
5. Download VNC and Extract to it's own folder.
6. Click Start, Select RUN, Press ENTER
7. Type: "C:\FolderName\WinVNC.exe" -sinstall

That will allow you to Install Silently so no pop-ups. If you need help to config or bring up other windows look for more commands here:

Don't forget to make the settings so when you use viewer it won't control all the time or people will know your on it. **ALSO SET A PASSWORD**

If you have anymore questions E-mail me directly or post here so that others can be helped as well.

You indeed can install programs without administrative rights! However these programs cannot create files or registry entries in secured areas (rights managment).

Ultravnc can be installed and run in such a user account (i do). However you cannot create services or the screen driver.

If you wisth to create a service you must execute the setup program by using the context menu : run as ...

Unfortunately the winvnc code contains a strange check, imho. It checks if a user belongs to the administration group and disables all property dialogs if not. There is no way to edit the properties in a short way. Instead you must log off, log on as administrator and change the value you want. The little service helper does not work with "run as" in context menu.

Finally i got angry of this behaviour and changed the source code.
In my unoffical version (1.0.1) these limitations are no more.
Instead you (as administrator) must allow the users write access to the registry path where winvnc.exe stores its properties (actual: HKEY_LOCAL_MACHINE\SOFTWARE\ORL)
I do not check for these rights, but all calls to winapi registry functions will fail and so no changes are made.
Maybe in a future release the property behaviour can be changed so that the menuitems are disabled if there are not enough rights for the actual user to change the registry keys (s.above)

You can download a winvnc.exe and the changed source from
