I ran into some trouble with Adobe Reader and opening .pdf, so I figured I would simply uninstall/reinstall it. Upon attempting to reinstall, an error comes up saying:
Error 1402. Could not open key: HKEY_LOCAL_MACHINE\Software\Classes\AcroExch.Sequence\DefaultIcon. Verify that you have sufficient access to that key or contact your support personnel.
I have no choice but to click OK, and then the installation rolls back and notifies me that nothing has been modified on my system. I went on Adobe's website and there was a tool that was supposed to fix errors 1406 and 1402, and that did nothing. After searching on other forums, there were suggestions of using Run As Administrator on the Adobe Setup and turning UAC on. Neither of those did anything. After another suggestion, I went into the Registry Editor to where the registry key listed in the error was and tried to change the permission. The AcroExch.Sequence folder can be opened and the permissions can be changed, but the DefaultIcon can't open at all. If I attempt it, I get an error that basically says Access is Denied.
I'm running Windows Vista, and I use Mozilla Firefox, in case that makes a difference.
Any help or insight as to why this is happening would be great.
