Operating System: Vista Ultimate
Product: Acrobat 8 ProfessionalWe have managed to install Acrobat 8 Professional and it works perfectly… with this one exception. Every time we start the computer, or click on a hard drive or such like we encounter a Windows Installer pop-up stating that it is preparing to install adobe acrobat 8… it then gathers information and completes…

It does this every time the computer starts and at random intervals in-between… and as you can imagine this is extremely annoying… so much so that at the moment I have completely removed this product from the computer.

 So how you fix it ?

Steps to resolve:

1. Follow all the steps to download SubInAcl - http://www.microsoft.com/downloads/details.aspx?FamilyID=E8BA3E56-D8FE-4A91-93CF-ED6985E3927B&displaylang=en

2. Open up Notepad (in accessories in the start menu)

3. Copy/Paste this code into Notepad, and replace the parts that say “YOURUSERNAME” with your actual user name:

cd /d “%programfiles%\Windows Resource Kits\Tools”

subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f /grant=restricted=r /grant=YOURUSERNAME=f /grant=restricted=r /setowner=administrators
subinacl /keyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f /grant=restricted=r /grant=YOURUSERNAME=f /grant=restricted=r /setowner=administrators

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f /grant=users=r /grant=everyone=r /setowner=administrators
subinacl /keyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f /grant=users=r /grant=everyone=r /setowner=administrators

subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f /grant=users=r /setowner=administrators
subinacl /keyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f /grant=users=r /setowner=administrators

4. Click File>Save As and save the document as registryfix.bat. Save the file to the folder that contains the SubInAcl program that you just installed.

5. Open that folder and click on the file, and the file will run. Let the file run completely until the window shuts itself. DO NOT end the process early.

6. Restart and your problems should be fixed

Let me know if this works for anyone else but it worked for me.
