C++ IDE code editor structure windows is blank on Windows 10 machine – workaround

by Aug 12, 2015

Several developers reporting an issue where the C++Builder IDE code editor structure window was blank after they upgraded their Windows machine to Windows 10. The issue is reproducible on these scenarios:

  • The user has a machine with a Windows version lower than Windows 10 (Windows 8.1, 8, 7,…)
  • The user has RAD Studio installed (all versions are affected)
  • The user upgrades to Windows 10

In our R&D testing, we have reproduced the issue on 2 machines after upgrading to Windows 10

  • Windows 7-32 bit with XE8 Update 1 installed
  • Windows 8.1-64 bit with XE9 23.0.20488.2497.1 installed

Once the upgrade to Windows 10 has finished, the structure pane for C++ applications is blank.

Microsoft has noted the issue with J# 2.0 on Windows 10. The workaround is:

  1. Uninstall the Microsoft Visual J# 2.0 Redistributable Package
  2. As the uninstaller is broken, you must enter into the registry and delete all the entries with 'J#'
  3. Reboot the machine
  4. Install the Microsoft Visual J# 2.0 Redistributable Package:

    • 64bit: http://www.microsoft.com/en-us/download/confirmation.aspx?id=15468
  5. Reboot the machine
