Error Message and wouldn't allow Adobe Acrobat Pro DC or Adobe Acrobat Pro Reader to Download

Hi @Jeff29898000paz1, 

Thank you for reaching out, and sorry for the troubled experience. 
First, if this office machine (IT-managed), you should reach out to your IT helpdesk. 

It seems you are already aware that: Error 1406 in Acrobat installation typically means that the installer can’t write a specific registry key due to insufficient permissions. Here’s how we can try troubleshooting and resolving this:

Fixing Acrobat Installation Error 1406

1. Run the Installer as Administrator

• Right-click the Acrobat installer (.exe) file.

• Select “Run as administrator.”

• This gives the installer elevated privileges to write necessary registry entries.

2. Temporarily Disable Antivirus/Security Software

• Some antivirus programs may block registry changes.

• Temporarily disable your antivirus and try installing again.

3. Manually Fix Permissions

If the error message points to a specific registry key (e.g., HKEY_LOCAL_MACHINE\Software\Classes...):

1. Press Windows + R, type regedit, and press Enter.
2. Navigate to the problematic registry key mentioned in the error.
3. Right-click the key > Permissions.
4. Select Administrators and ensure Full Control is checked.
5. Click OK and retry the installation.

4. Use the Acrobat Cleaner Tool

If the issue persists, clean out previous installs.

• Download: Adobe Acrobat Cleaner Tool

• Run the tool, restart your machine, and reinstall Acrobat.

Let us know how it works.
