Hi, hopefully the title kind of explains the general situation. I have a Compaq Presario C500 Laptop with Vista Home EDITION installed (Intel Celeron M CPU 1.86 GHz/1.50 GB Ram/Vista SP 2.
I've been trying to update my Adobe Reader 8 to a version 9 or 10. However, each and every time I try to install either, I receive 3 error messages (1 of them stating the following: "Error 1402. Could not open key. HKEY_LOCAL_MACHINE\Software\Classes\AcroExch.Sequence\DefaultIcon. Verify you have sufficient access to that key, or contact your support personnel."
The second message STATES: "Error 1402. Could not open key. HKEY_LOCAL_MACHINE\Software\Classes\PDFShellServer.PDFShellInfo2.1\CLSID. Verify you have sufficient access to that key, or contact your support personnel."
The final error message states: "This file does not have a program associated with it for performing this action. Create an association in the Set ASSOCIATIONS control panel."
This also happens when I try to completely uninstall Adobe Reader 8 as well. Can anyone help me? Thanks!
http://kb2.adobe.com/cps/329/329137.htmlThanks for replying - I've tried that page. The problem is when I get to this section: 3.Back up your current Registry file:
a.In the Registry Editor dialog box, choose File > Export
b.Type a name for the file and choose the location. No matter what I type for a file name, it won't accept it.Did you uninstall version 8 before trying to install a later version? This is ONE of the reason I am not happy with Adobe products. They slow down PC speed and also difficult to remove from system. They act like a virus. So know I am using another PDF editor named as classic PDF reader.

It works great.Quote from: freeforall on August 24, 2011, 02:06:36 AM

Foxit Reader also is a great alternative to Adobe Reader.
