Installing Visual Studio 2005 SP1

Did you try installing SP1 for Visual Studio without any errors? If not or if you are still did not start the installation some of the following details will help.

 

The list of things that Microsoft had fixed in Visual Studio 2005 SP1 is located at http://support.microsoft.com/?kbid=918526.

Most of the time the setup will fail due to the insufficient disk space. So before trying to install the SP1 check whether you have at least 6.3 GBs of free disk space. If you have installed VS in other partition than Windows I recommend to check for free disk space in both partitions.
Another common error which can happen when installing this is,

Error 1718. File FileName was rejected by digital signature policy.

This error is due to the Software Restriction Policies (also known as SAFER) that exist in the operating systems that came after Windows XP. This was introduced to help users avoid running unsafer files. SAFER will be used by Windows Installer to check the file signatures to confirm that the files were not tampered. Note that this error can happen when installing any large Windows installer package or Windows installer patch.

This error occurs when there is no contiguous piece of virtual memory to accommodate the file. Then the Windows installer will fail to validate the file and result in this error.

There are few things you can do to fix this,

1. You can edit the registry to make the PolicyScope value to 1 before you install  the package.

2. By changing the SAFER settings to allow administrators to install the package.

3. Installing the hotfix if you are running Windows 2003,

For any of this you can get more information from Microsoft by visiting

Even though I had no luck recovering the applications without formatting the system which crashed with the failed installation of Visual Studio SP1, I guess you will have much more luck after reading these articles.
