  1. I encountered this problem when trying to install the usb drivers for a Huawei MT841 modem.

    Now I am getting this error when trying to use Add/Remove Software.

    Googling indicates that this could be due to:
    1) Virus
    2) Damaged/deleted newdev.dll caused by software installation/uninstallation

    Remedies suggested:
    1) Uninstall IE8, get latest IE8 Installer, reinstall IE8
    2) SFC /ScanNow
    3) “The safest method to fix Newdev.dll error is to make a complete scan for your poorly maintained system with a trustworthy Newdev.dll error repair tool on your computer. It is specifically designed to ensure you a thorough scan and repair for the system which has been mostly ruined by Newdev.dll error and other frustrating system problems with its ultra powerful and advanced PC error detection tools.”

    Any feedback/suggestions would be greatly appreciated.

    I have a fully updated XP SP3.

    I also have XP Pro SP3 installed.

    I find newdev.dll in C:\Windows\system32. Rt click it Properties->Version tab says v5.1.2600.5512

    You can download Hashtab will install a File Hashes tab on Properties. My version of that dll shows an MD5 hash value 03C76895F47A1339A697269000675266 (copy/paste my md5 value into your hash tab Comparison field, click Compare button

    I'll post the Security tab permissions later when I get the chance

    Thank you, Lookin.

    The file version and MD5 of my newdev.dll are the same as yours.

    And, thanks for the Hashtab link.:)

    Hi Ravi! :)

    You're most welcome! I find that HashTab tool pretty handy for easily calculating and comparing file hash values.

    Let's check your newdev.dll file permissions next. This is what I see when I select either Administrators or System on the Security tab

    and this when I select either Power Users or Users

    For the sake of closure :

    newdev.dll has quite a few dependencies.

    So the best course of action was ro reformat & reinstall.
