Error 1310 writing to file: C:\Config.Msi

This error is something I posted back in January 2008, I originally had this problem installing office 2007 with carbonite causing the problem, but it does seem to occur with many other different programs as well.

Frank asks:

I have encountered this problem installing an upgrade of adobe reader, when I uninstall the ask toolbar from internet: error 1310 writing to file: C:\Config.Msi\ec69a.rbf. Please verify that you have access to that directory. My system is Windows7 and I’m the administrator.

There are a number of ways of dealing with this problem, firstly turn off any sync programs such as iDrive or Carbonite as these tend to interfere with this process.

Method 1

Unregister Windows Installer, and then reregister Windows Installer. To do this, follow these steps:

  1. 1. On the “Start” menu, click “Run:.
  2. 2. In the “Open” box, type “msiexec /unreg”, and then press ENTER.
  3. 3. On the “Start” menu, click “Run”.
  4. 4. In the “Open” box, type “msiexec /regserver”, and then press ENTER.

Method 2

The Windows Installer service may disabled on the machine.

  1. 1. Go to “Start” -> “Run” , type “services.msc” and press on “Enter” button.
  2. 2. Double-click on the service named “Windows Installer”.
  3. 3. Check the value in the “Startup type:” field. If it’s currently set to “Disabled”, then this is the problem. Change it by selecting “Manual” from the drop-down box.

Method 3

Empty user and system “temp” folders.

  1. 1. Empty “%systemdrive%\temp” folder.
  2. 2. Empty “%systemdrive%\%windir%\temp” folder.
  3. 3. Empty “%systemdrive%\Documents and Settings\%username%\Local Settings\Temp”.

Method 4

Check if there is pending installation/s:

Warning: You should only edit these registry entries if you really know what you’re doing. Back up your hard disk first.

a. Empty “InProgress” Registry Key

Check the following registry key:


and clean any entries that you find.

b. Empty/Rename “PendingFileRenameOperations” Registry Key:

Check the following registry key:


and clean any entries that you find.

Mailbag 23/09/2010 – Windows 7 Server Mode

The main problem I have been hearing this week is people using windows 7 as a file server or people trying to access their windows 7 machine in some way from a Windows XP machine. This is fine if the windows 7 pc gets regularly restarted, the reason for this, not fully known to me, is that windows 7 has an issue with memory allocation to system non-paged pool.

You may be getting this error log issued to your event logs:

Source: srv
Event ID: 2017
Level: Error
Description: The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.

The fix is just a simple registry change below:

Set the following registry key to ‘1′:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

and set the following registry key to ‘3′:

This should definitely sort out the problem, if not please let me know.

I found a fix many months ago unfortunately I am unsure where I got it from, so I am not able to give recognition to the correct person.

Howto: Change Windows XP Product Key without a Reinstall for WGA

Windows Genuine Advantage is now a required install. If you need to change your product key without an installation to make WGA happy, these steps will walk you through it. This uses Microsoft-supported software. This is how I explore “You May Be a Victim of Software Counterfeiting” errors.

Many of our users at work have been receiving the You May Be a Victim of Software Counterfeiting error. Basically what happened was that the notebooks were mailed with invalid product keys.

Surprisingly for many people, the Certificate of Authenticity (COA) or supplied valid product key may not be the actual one in use on their desktop computer or laptop. These numbers can be found on your XP software box or on a COA sticker on your system.

First, compare the product key on your XP installation to your valid xp product key or COA number using WGA Diagnostic Tool.

If the numbers are different, you can usually change your number to a valid one by using Microsoft’s Key Update Tool.

Product Key Invalid When Reinstalling Windows 7 Student Version

We were recently contacted by a reader who encountered a problem when trying to reinstall a Windows 7 Professional student version from Digital River. The product key was not accepted during installation even though it had been accepted during the first installation of the operating system.

It was possible to continue the installation without the product key. Windows 7 however did not accept the product key after installation displaying the error code 0xC004F061 in the activation window. The description read “The Software Licensing Service determined that this specified product key can only be used for upgrading, not clean installations”.

Microsoft did however confirm in numerous occasions that it is possible and allowed to perform a clean install with a Windows 7 Student version.

Research on the Internet revealed another user with the same problem who posted on the official Microsoft support forums. This user received instructions from Digital River on how to resolve the invalid product key issue.

Open regedit.exe with Start Menu Search and navigate to:

Change MediaBootInstall from “1? to “0?. Close RegEdit.

Start Menu on the Command Line utility. Right-click this shortcut and choose “Run as administrator.” Click Yes to the UAC prompt.

In the command line window, type: slmgr /rearm press enter wait for the “Command completed successfully” dialog.

Then, close the command line window and reboot.
After Windows 7 reboots, Right Click Computer select Properties select change product Key.

If the Key does not work now please contact Microsoft technical support at:

Hope this helps everyone who is seeing the same product key invalid error when reinstalling a student version of Windows 7.
