How can I reinstall BitLocker on Windows 7 Home Premium.

I would like to re - install BitLocker, after uninstalling previously by the "Control Panel".  I proceeded to search my hard drive for files, including the words "BitLocker" and found several remnants of the request, including "BitLocker to Go.mui" and three executable files. At the launch of the "BitLockerWizard.exe" application, a 'System error' window explains that "the program can't start because BDEHDCFGLIB.dll is missing on your computer. Try reinstalling the program to fix the problem.
The Panel gave no indication of which allows me the opportunity to re - initialize program.
It is a service of BitLocker, and when I start it up, nothing seems to change, and there is no process newly listed in the Task Manager console. Description name service "Host BDESVC" and explains that he is there to facilitate many BitLocker operations.
Short of completely reinstall Windows 7, how do I re - install Bitlocker?

BitLocker is not available in Windows 7 Home Premium.

It is only available in editions of Windows 7 Ultimate or enterprise.

You can use a third-party free alternative like TrueCrypt:

If you want to use BitLocker, you must upgrade Ultimate:

  • How can I get a valid Windows Vista Home Premium product key for my Acer Aspire 5050?

    My hard drive failed in my Acer Aspire 5050.  Replaced, reinstalled Windows Vista Home Premium with the appropriate product key, but Microsoft says that it is invalid.  Microsoft wants to buy me a new copy of Windows & there is no available from Acer for my laptop recovery disk.  What can I do?

    The product key on the bottom of the laptop is an OEM product key.  This product key does not work for the commercial versions of the operating system.  The original shipping charge might work on the system without entering a product key.

    If you did not, or are no longer able to get the recovery media, you will have to buy an operating system of your choice for the installation.

  • How can I change RWIN in Windows 7 Home Premium?

    I contacted my ISP at slower speeds, when I promised 100 Mbps. I have 100 Ultra Charter, and after contact, they said I can have incorrect MTU and RWIN values. They recommended:

    MTU 1500
    RWIN of 1048320
    I already changed the MTU, but how do I change RWIN?

    Hello

    You can't reinstall Vista on a recovery partition you have installed another operating system

    read this:

    Solve a common problem of recovery.
    If the original operating system is changed to a non - Vista OS, the Recovery Manager cannot be launched either office or by pressing f11 at startup. You can use the recovery disk to restore the computer to the original state of Vista. If you are using a non - Vista OS, you can use a third-party partition management program to recover hard disk space.

    ________________________________________________________

    Contact the manufacturer of the laptop computer and ask them to send you to vista recovery disks to reinstall the operating system back as it was when you bought it

    they do it for a nominal cost of $

    you say, that they will not!

    ________________________________________________________

    or borrow a vista microsoft dvd; not a HP, Acer recovery disk etc

    Make sure that you borrow the correct 32-bit or 64-bit microsoft dvd to your computer

    they contain all versions of vista

    This is the product key that determines which version of vista is installed

  • How do I upgrade/switch to Windows 7 Home Premium 64 bit OF Windows 7 Home Premium 32 Bit?

    I noticed that my laptop has 64-bit capabilities. My processor is AMD Athlon Dual-Core QL-60 1.90 GHZ. Can someone give me detailed instructions on how to move to Windows 7 Home Premium 64 Bit? Also, I have 2 GB of RAM, and I don't know if I should get another 2 GB for the transition to work. Thank you. ~ Mystery.

    @LVTravel my laptop came with Windows Vista installed, but last Christmas, I installed Windows 7 Home Premium. It actually came with 64-bit disk, and the activation key.

    I understood the part when you say that I have to reinstall all my programs basically. I'm not sure what you mean by data files, they are available when I insert the backup? Where can I insert the disc to backup at all? My question is, how to restore these "data files"? Also, sorry for all the questions. :)

    ~ Mystery.

    Data files are the files that you create with your programs such as movies of documents, spreadsheets Excel, Word, photographs, etc.  If the files have been copied on the device to backup using Windows Explorer you can just copy them to the refurbished computer.  If you used a backup of some program you type then need to use this program to put the files back on the computer.  Some backup programs will create an image of the drive hard and if you do not select the data files only you could possibly replace your 64-bit operating system installation.  I would recommend that you get your cousin to ensure that data is backed up and the restore is performed correctly.
     
     
  • How will I know if my Windows 7 Home Premium x 64 or x 86?

    I have a 64-bit computer, but there are files on the C drive for Program Files and Program Files (x 86). I have questions on this topic, but do not actually need to know, so far. I'm trying to restore my backup files in when I upgraded Vista to Windows 7 Home Premium. I discovered an additional file/application had to be downloaded to achieve this, but unfortunately I do not know that you choose. x 64 or x 86.

    I have a few questions:

    I chose Custom installation because I wanted to wipe my hard drive and reinstall just some things. I just discovered that a file was created on my computer as "old computer." If she was going to do this, why did I have to lose a day and 17 discs, backup files?

    When I am able to restore the backup, I can choose what get-restored or am I stuck with everything? I think I deleted everything I didn't until I did the back-up, but just in case I would like to be able to choose what is restored to my computer.

    I have a ton of papers of college in the end so I have to get my MS Office Suite restored to this computer, so if someone could help me quickly, I would really appreciate it.

    Thank you!!
