"Unrecoverable build error" (an unrecoverable build error) error message appears when you generate and deploy a project.

Environment: win2003server + vs2003
An error occurred while generating the installation file ".
Previously normal, but this time I added a reference to the COM component,

Using ADOX;

// Create an Access File
ADOX. catalogclass cat = New ADOX. catalogclass ();
Cat. Create ( @" Provider = Microsoft. Jet. oledb.4.0; Data Source = " + File + " ; " );
Cat = Null ;

For the added reference of COMCodeAfter this code is added, a problem occurs.
I started to think that it was caused by adding references to com. But I checked the information and said
This problem is generally caused by a low version of the C:/program files/common files/Microsoft shared/Msi tools/mergemod. dll file. You only need to download a new version and register it.
Download the new mergemod. dll and solve the problem after registration.

• In Your Visual Studio. NET project, Multiple folders have the same name.
• Some interfaces in the Registry are missing.
• In the registry, mergemod. dll is not registered or an incomplete mergemod. dll version is registered.
• You have upgraded from Visual Studio. NET beta 2 to release.

 

Solution
• Too many open code and design windows
To solve this problem, close all startup, code, or design windows that are not used in the Visual Studio. NET Interactive Development Environment (IDE. You can access these windows through the tabs or the MDI type of the IDE workspace.
• Multiple folders with the same name
To solve this problem, specify a unique name for each folder in the Visual Studio. NET project.
• Registration loss
Warning if the registry is incorrectly modified using the Registry Editor or other methods, it may cause serious problems. These problems may need to be solved by re-installing the operating system. Microsoft cannot guarantee that you can resolve these problems. You are at your own risk to modify the registry.

Set the default value to ienumvariant.
• Hkey_classes_root/interface/{00020404-0000-0000-c000-000000000046}/nummethods

Arui's explanation:

Today, I am working on an installation project. during compilation, there is always an "irreparable generation error", so I am rolling over the mountains and wading through the mountains, finally, the problem was found in C:/program files/common files/Microsoft shared/Msi tools/mergemod. the dll version is incorrect ~~~~, Version is 1.20.1827.1, the latest version is 2.0.2542.0, on the Internet to find A, when the next, re-register a solution, here also introduce you to a professional search DLL website http://www.webzila.com /? WZ = DLL, pretty good
