[.NET General] SQL Server Express "incompatible components" failure
Having faced the same problem, the absence of sqlbuw.exe, I have found another solution that might help you get the necessary files.
- Go through the same install to the point where the error dialog box is on the screen.
- Explore your hard drive and you should see a temporary directory where the SQL Server Express installation files are being cached. It will be named with a bunch of hexidecimal numbers, probably right under the root on your C:\ drive.
- In that directory, find subdirectory "setup tools."
- In "setup tools," you should see a "build uninstall wizard" subdirectory.
- Copy the "build uninstall wizard" subdirectory to some temporary location on your system.
- Kill the install
- Run sqlbuw.exe from the command line in the temporary directory you copied.
