Windows 10: Where can I find the 64 bit version of bcrypt.dll?

I've encountered the "DLL load failed: %1 is not a valid Win32 application" error and have tracked it down to bcrypt.dll. I checked and sure enough we still have the 32 bit version in our image. I'm looking for a trustworthy location to download the 64 bit version.

Error during iTunes installation in Windows 10 64 bits version

Hi,

Thank you for posting in Microsoft Community.

As you said that " it worked fine with 32-bit version", and there is a problem in installing in 64-bit version. But iTunes application is compatible with both the versions. There may be an issue with the PC which/iTunes application which is not supporting
the particular PC.

The error code which you have provided is related to Windows update.

I suggest you to run the Windows update troubleshooter and check if it helps.

You can follow the steps:

• 
  Type Troubleshooting in the search box present in the Taskbar.
  
• 
  Select Troubleshooting.
  
• 
  Select View all on the top left corner.
  
• 
  Run Windows update Troubleshooter.
  

Let us know the status of the issue.

Thanks.

 

Windows 10 Upgrade 32-bit to 64-bit

So, Windows 10 Upgrade is being rolled out worldwide, and I have 'reserved' my upgrade.

Currently my computer is running Windows 7 Pro 32-bit. I'm planning to 'upgrade' it to Windows 10 64-bit (via fresh install, of course).

After reading many references, these will be the steps I'll do:

1. Let the "Get Windows 10" app upgrade my OS to Windows 10 32-bit
   
2. Note the activation key
   
3. Download the Installation Media for Windows 10, but choosing 64-bit instead
   
4. Perform a clean install
   
5. Reactivate using the activation key in Step #2
   

(Of course I'll backup my data first.)

However, I still have some questions:

1. On Windows 7, the activation key does not differ between 32- or 64-bit versions. Is it still so with Windows 10?
   
2. Will I be able to download a different architecture on Step #3?
   
3. Is there anything I need to prepare beforehand?
   

Thank you for your assistance.
