The IDE may flash briefly and disappear without any error message.
CAUSE
The IDE startup error has occurred in the following situations:
- The IDE was not able to load Msxml3.dll.
- The IDE was not able to load Mso.dll.
- The IDE was not able to load DTE.olb.
- The license key for Visual Studio .NET was not created during setup.
- Script blocking is turned on and not allowing scripting code to execute.
- The .NET Framework setup portion of Visual Studio .NET failed to generate a valid native image for mscorlib.dll.
- The Klez virus is present.
The first is the more common situation. It results from a known problem in which the installation fails silently during setup in certain computer states.
RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
IDE unable to load Msxml3.dll
The July 2001 Beta release of the MSXML 4.0 Technology Preview has left the computer in a state that causes this behavior. To repair the Msxml3.dll registration, follow these steps:
Note If you have not already applied the latest security updates for MSXML, download the file from the following Microsoft Web site:
- Unregister Msxml4.dll. To do this, click Start, click Run, type regsvr32 /u c:\winnt\system32\msxml4.dll at a command prompt, and then click OK.
- Run the installation of the security update.
- Download the registry key from the following Microsoft Web site, and then incorporate the values by double-clicking the Fixxml4.reg file:The following file is available for download from the Microsoft Download Center:

IDE unable to load Mso.dll
Use any or all of the following to fix the Mso.dll problem:
- Make sure that you are NOT running a Microsoft Office XP beta release.
- Run a repair installation of Office XP.
- Make sure that the following registry key is set correctly:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.0\Path] "MSO"="C:\Program Files\Common Files\Microsoft Shared\Office10\MSO.DLL"
IDE unable to load Dte.olb
Register dte.olb with the command below:
regsvr32 "C:\Program Files\Common Files\Microsoft Shared\MSEnv\DTE.OLB"
License key for Visual Studio .NET not created during setup
The Visual Studio .NET splash screen does not contain information on what products where installed and the splash screen does not contain the end user who installed the product. Also, Visual Studio .NET in Add/Remove programs for the current user is not present. The suggested solution is to completely remove Visual Studio .NET and reinstall.
Script blocking is turned on and not allowing scripting code to execute
Warning This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
The Visual Studio .NET IDE flash is not displayed and disappears if third-party script blocking is turned on. This has been seen with Norton Antivirus 2002. For additional information, visit the following Symantec Web site:

.NET Framework setup portion of Visual Studio .NET failed to generate a valid native image for Mscorlib.dll
The Visual Studio .NET splash screen is displayed briefly and then disappears if the .NET Framework portion of Visual Studio .NET setup failed to generate a valid native image for Mscorlib.dll in the \%windir%\assembly\NativeImages1_v1.0.3705\mscorlib directory. The suggested solution is to uninstall the .NET Framework and reinstall the .NET Framework to regenerate a new Mscorlib.dll in the \%windir%\assembly\NativeImages1_v1.0.3705\mscorlib directory.
Klez virus
Important These steps may increase your security risk. These steps may also make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We recommend the process that this article describes to enable programs to operate as they are designed to, or to implement specific program capabilities. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular environment. If you choose to implement this process, take any appropriate additional steps to help protect your system. We recommend that you use this process only if you really require this process.
You may also receive this error message if your system is infected by the Klez virus. We recommend that you obtain the most recent update to your antivirus software, and then do a system scan.
