Are you installing as an Administrator user?
If yes, see this article http://kb2.adobe.com/cps/329/329137.html
If that doesn't help, remove your Adobe Reader installation with the Windows Installer Cleanup Utility (http://majorgeeks.com/Windows_Installer_CleanUp_Utility_d4459.html), then install the latest Reader 9.4 from http://get.adobe.com/reader/
It looks like you do not have access to a specific registry key.
This might be due to the fact that you may not be added to the Administrators group or the registry key has been denied access explicitly to a group that you may be part of.
You can follow the below mentioned steps to rectify your issue as well:
- Download Microsoft's SubinACL tool from http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe -4a91-93cf-ed6985e3927b
- Install the same by double clicking on the "subinacl.msi" just downloaded.
- Open Command Prompt window through the Run Dialog Box (Start | Run, type
cmdand click OK)
- In the Command Prompt window, type in or copy/paste the following commands:
cd /d "%ProgramFiles%\Windows Resource Kits\Tools"(Hit Enter)
subinacl /subkeyreg <type the registry key for which you are getting the error 1402> /grant=administrators=f /grant=SYSTEM=f /grant=USERS=f /grant="Creator Owner"=f(Hit Enter)
You should see some processes happening on your screen. After the process ends, retry installing the updates. Hopefully, they should succeed now.
