I recently had this problem after buying a voyager 210 modem/router to replace the voyager 105 (in my case supplied for AOL broadband)

I tried to uninstall the voyager 105 and encountered exactly this problem - newdev.dll missing, Admin privileges required

After alot of Internet searching I found no answers. But in desperation tried this and it worked. I am by no means any computer expert so don’t blame me if this does not work for you, or damages your machine.

To install my 210 modem I was following instructions found here -http://www.sohodata.co.uk/soho.htm But first I had to get rid of the 210

Here is what I did, exactly as I did it (some of it is probably unnecessary) Further below is a condensed version I expect would work.

1) Firstly I restarted in safe mode by pressing F8 in start-up ( I was doing this because i had remembered an administrator profile and considered attempting to uninstall from there.)

2) I logged on as the administrator.

3) Attempted to uninstall the voyager 105 via control panel and via the uninstall icon in the programme folder. - Both Failed with the above-mentioned problem.

4) I navigated to programme files. (Start> My computer> C drive> Programme files)

5) There I highlighted the folders "British Telecom”, "BT Voyager 105 ADSL modem", " Voyager Modem Drivers", "Voyager Test". I cut these folders wholesale and pasted them to my USB pen/stick (incase I needed to put them back)

6) I then ran disk cleanup (Start> All Programmes> Accessories> System Tools.)

7) Then I turned off my computer and unplugged the USB pen/stick and the USB and DSL cables from the back of the Voyager 105.

8)I turned the computer back on (starting up normally), logged on with my normal username which has admin privileges. Ran the driver install for my new router (previously downloaded from BT at –(http://www.btopenworld.com/broadband/adhoc_pages/driver_homepage.html#yahoodrivers) It stated that a BT driver was already installed.

9) Navigated to add/remove programmes (Start> Control panel> add/remove programmes) selected the BT driver from the list selected uninstall …. AND IT DID IT! No error, or messages about newdev.dll or privileges.

10) This left me free to install my new driver and go through its install process ending in plugging the USB into the back of the modem and having internet again.

Here is what I expect would work

1) Turn on and log on to any account with admin privileges.

2) Navigate to programme files. (Start> My computer> C drive> Programme files).

3) Select and delete (or to be safe, cut and paste to a removable drive) the folders "British Telecom", "BT Voyager 105 ADSL modem", " Voyager Modem Drivers", and "Voyager Test".

4) Remove removable drive and run disk clean up (Start> All Programmes> Accessories> System Tools).

5) Then I turned off my computer and unplugged existing modem.

6) Turn on computer log back onto account with admin privileges. Navigate to add/remove programmes (Start> Control panel> add/remove programmes) selected the BT driver from the list selected uninstall.

7) Install desired drivers/modem.

If you find this works for you too and have asked this question elsewhere, please copy this solution so others can solve this problem too

If you have IE-8 installed, then uninstall it and it will start working.
You can uninstall IE-8 using this command in the run dialog box:
"C:\WINDOWS\ie8\spuninst\spuninst.exe

There seems to be conflict with IE8 - try unistalling IE8 and try again.

I was working at one of Lithuanian internet service providers. We often had clients complaining about ZTE 831 connecting through USB. The answer is - use a LAN card. Sorry.

Most of the time the XP drivers for modems also works for Vista. I suggest You try force install of your XP driver. Also check the website for the manufacturer if they released a Vista driver.


Hope it works.
