“Error while unpacking program, Code 2. Please report to author” error when launching or installing a Nuance product."

This is an article I have copied from Nuance website since I always encountered this in our clients which are using MS Vista. So for me to remember and easy to find, I'm putting this on this blog.

Problem:

When launching or installing a Nuance Desktop product on a Windows Vista Operating System, the following error may appear:

Error while unpacking program, Code 2. Please report to author

Note: This error may occur when using the following Nuance software:

• Dragon NaturallySpeaking
• PDF Converter Professional
• PDF Converter
• PDF Create
• OmniPage
• PaperPort

Cause:

Microsoft released a new security update for Windows Vista on July 11, 2011 (KB2533623) that has caused problems with certain software.  Problems that may occur include not being able to launch or install certain third party applications on Microsoft Windows Vista. 

Solution:

We are aware of this issue and are currently working with Microsoft to resolve the problem.  Until this issue is resolved, the only way to continue using the Nuance application is to remove the specific Microsoft update. 

To remove this KB2533623 Windows Update, follow the steps below:

1. Click "Start > Control Panel > Programs and Features".
2. Click the "View installed updates" link on the left side of the window.
3. Locate the "Update for Windows Vista for x64-based Systems (KB2533623)" update.
4. Select the KB2533623 update and then click the "Uninstall" button.
5. Once the update has been removed, restart the computer.
6. After the computer restarts, confirm that the Nuance Desktop application can now be launched or installed.

Cannot open your default e-mail folders.

I'm having this problem for two days. One of the users in the remote site cannot use her Outlook 2007 and she's getting this error message in the PC that she's using. She's connected to the MS Exchange 2007 located in the main site through VPN. By the way, VPN connection is connected perfectly. I connected to her system by means of a remote software. Her Outlook is completely appearing disconnected. It seems that the Exchange Server cannot resolve the username of that use.So I decided to go to the remote office and setup 

her email on my laptop but is running smoothly. I configured it easily without experiencing any problem.

So I created a new profile for the Outlook and I get this error:

"Cannot open your default e-mail folders. The file C:\Documents and Settings\USERNAME.DOMAIN\

Local Settings\Application Data\Microsoft\Outlook\outlook.ost cannot be accessed. You must connect to your Microsoft Exchange Server computer at least once before you can use your offline folder file."

To fix this problem, here are the steps that I took:

1. Open Control Panel - Mail

2. Create a new profile

3. Specify the Microsoft Exchange server or the FQDN

4. Put the username or the name of the user 

5. Dont click on the check name tab, instead go to More Settings >Security  and put the tick mark on encryption and click Apply.

6. Now you can click on the "Check Name" and now it will resolve the name.

Hope this helps!

Good luck!
