Q: I've installed TeeChart4.03PRO for Delphi 5 and now I cannot use Decision Cube. How can I remedy this ?

This solution is applicable only for Delphi 5 Enterprise edition (or if you have Decision Cube source code). 

1. Download and install TeeChart4.03PRO for Delphi5.
2. Go to the "Components->Install packages" and remove "Borland Decision Cube components" with the "Remove button.
3. Locate Decision Cube source code. It should be located in the Delphi5 \Source\Decision Cube directory.
4. Open DSS50.dpk package. Remove the Tee50.dcp package. Add (on the same place) Tee45.dcp package. Try to recompile. If you get  a complaint about using "always built package with the never built...", do the following : Click "Options" speed button. Change "Build control" to "Rebuild as needed". Try recompiling again.
5. Open DclDSS50.dpk package. Remove the DclTee50.dcp package and replace it with the DclTee45.dcp package. Change "Build control" to "Rebuild as needed" and recompile.
6. Copy DSS50.bpl to Windows \System directory, DclDSS50.dpk to Delphi 5 \Bin directory and all *.dcu and *.dcp files to Delphi5 \Lib directory.
7. Go to the "Component->Install packages" menu and click "Add" button. Then pick the DclDSS50.bpl package, located in Delphi5 \Bin directory.
