I am trying to install powershell 5.1 (KB3191566) on my windows 7 laptop. Installation terminates just saying that it failed. Most of my searches lead me to this forum, where I found out that this problem is not that uncommon, but each solution is different for a particular computer. So I run SURT (KB947821) but that one ended saying that it's not installed either. As I thought that my problems affecting KB3191566 installation might have been solved anyway, I run that one again but this time it just got stuck on 'Initializing installation'. So I cancelled it and gave SURT a second chance. It finished the same way as the first time.

Previously I have tried everything: installing WMF 4.5, 5.0; trying with .NET framework 4.5, 4.7.2 and 4.8. Nothing worked, each WMF installation failed.

ComponentsScanner reported 4,000 issues or so. I am attaching exported CBS folder and scanner report.

Many thanks for your help.

Hello and welcome,

There are some registry corruptions to be fixed.

Step 1:
Export registry as hive
  • Click on the Start button and in the search box, type regedit
  • When you see regedit on the list, right-click on it and select Run as administrator.
  • When regedit opens, using the left pane, navigate to the following registry key and select it by clicking on it once.
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing

  • Once selected, click File > Export....
  • Change the Save as type: to Registry Hive Files (*.*).
  • Name this file ComponentBasedServicing (with no file extension) and save it to your Desktop.
  • Right-click on the saved file and choose Send To -> Compressed (zipped) Folder.
  • Attach the .ZIP file to your next post.
  • If the file is too large to upload here, please upload to Gofile or WeTransfer and just provide the downloadlink here.

Step 2:
Provide the Components Hive
1. Navigate to C:\Windows\System32\Config and locate the COMPONENTS file.
2. Please copy this file to your desktop.
Note: If you receive an error that this file is in-use, simply reboot your computer and try again. Note: If you find that you need to reboot and are unable to because this is a server then try Option#2 below.
3. Right-click on this file on your desktop and select Send To...Compressed (zipped) folder. This will create a file named COMPONENTS.ZIP on your desktop.
4. The file will likely be too large to upload here so please upload to Gofile or WeTransfer and just provide the link here.

Option#2 (only if you are unable to follow the previous instructions)

  • Please download the Freeware RegBak from here: Acelogix Software - Download products
     You will find it at the bottom of the page that the link brings you to.
  • Go ahead and install this program and accept all the defaults. After the last install screen the program should open.
  • Click the New Backup button. Accept the defaults and simply click Start.
  • When it says Finished successfully, click the Close button.
  • This will bring you back to the main screen of the program. You will see one entry in this list with the date that you did it. Right-click on this line-item and select Explore Backup...
  • This will bring you into the folder where the backup was made. You should see a Users folder and a Windows folder along with a couple other files. Double-click on the Windows folder to open it. Then open the System32 folder and then config folder. You should see around 6 files in here, one of which is named COMPONENTS.
  • Copy the COMPONENTS file to your Desktop. If the COMPONENTS file does not exist, please fetch it instead from C:\Windows\System32\config\COMPONENTS.
  • Now right-click on the COMPONENTS file that is on your desktop and select Send to > Compressed (zipped) folder.
  • Then please upload the zip file (COMPONENTS.zip) to your favourite file sharing website (it will be too big to upload here). Examples of services to upload to are Gofile or WeTransfer and then just provide the link in your reply.
  • You can close any open windows you have as well as the RegBak program now.

Provide a fresh copy of the components hive.
 
I removed a corrupt registry key from your COMPONENTS hive.

I have managed to rename the existing COMPONENTS file right away and replace it with the new one. There were no errors, neither after replacing the file nor after rebooting the system.
 
Great.

Follow the instructions below to run a scan with the System Update Readiness Tool (SURT) and provide a log.
  1. Download SURT for your system. (Windows 7 SP1 x64)
  2. Once downloaded, execute the installer, and go through the installation (this process can take around 15-20 minutes).
  3. On completion, a log will be created in C:\Windows\Logs\CBS\CheckSUR.log.
  4. Attach this log to your next reply.
Alternatively, if these instructions are unclear for you, you can follow the tutorial below.

Indeed it lasted 15 minutes. I haven't noticed progress bar moving, but installation itself reported no errors. Here is the requested log file.
