SYMPTOMS
When you build a Visual J++ 6.0 solution, the build process fails, and the following error message appears in the output window:

Solution Update Failed

No further compilation errors are listed in the task list.



CAUSE
This problem occurs when you have an incorrect version of COMCAT.dll installed.



RESOLUTION
To resolve this problem, follow these steps:  Search your hard disk for all the copies of COMCAT.dll. Rename all of them except for the one in C:\%windir%\System32 folder, where %windir% represents your operating system folder. There are two versions of COMCAT.dll on C:\%windir%\System32:  Version 4.71: 22 KB (Correct version) Version 5.00: 6 KB (Incorrect version)

 On the Start menu, click Run, and type the following command to unregister COMCAT.dll version 5.0:

regsvr32 /u Comcat.dll

 Delete or rename the incorrect COMCAT.dll file in the C:\%windir%\System32 folder.</li> Copy COMCAT.dll version 4.71 from the Visual J++ 6.0 CD-ROM to the C:\%windir%\System32 folder.

NOTE: You can find the correct version on the CD-ROM in the \Common\Ide\Ide98\Redist folder.</li> On the Start menu, click Run, and type the following command to register COMCAT.dll version 4.71:

regsvr32 Comcat.dll

</li> In Control Panel, click Add/Remove Programs, click Microsoft Visual J++ 6.0, and then click Reinstall to repeat the last installation to restore missing files and settings.</li> Restart the computer.</li> Start Visual J++ and rebuild your project.</li></ol>

If you still receive the &quot;Solution Build Failed&quot; error with nothing in the Task List, upgrade to the latest build of the Microsoft virtual machine for Java from the following Microsoft Web site:
