How to: Reinstall VCL Components from Scratch

The following instructions allow you to address most issues that may occur during the installation process, such as linker and compiler-related errors after an upgrade:

  1. Run the VCL component installer and select Remove to uninstall our products completely.
  2. Manually delete all DevExpress-related files (BPL, PAS, HPP, DCU, etc.) that may remain after the uninstall operation. All required file names always start with dx and cx prefixes.
  3. Launch your RAD Studio IDE and delete invalid paths from Library Path and Browsing Path lists.
  4. If you have any custom packages based on DevExpress packages, remove these packages.
  5. Close your IDE and remove all invalid paths from the PATH environment variable manually.
  6. Make sure that all patches and updates are installed for your RAD Studio IDE version.
  7. Restart your PC.
  8. Login as Administrator and install DevExpress components from scratch to a folder with a short absolute path, such as C:\DevEx\ (because long installation paths may cause issues).
