Default Library Path

Question

Prior to my problem, I attempted to install a component which required me to change my Library - Win32 library path. The installation did not work out so I left it. A few days ago, I ran Delphi to work on my project. I compiled the program but Delphi told me "Unit not found: 'Systems.pas' or binary equivalents (.dcu) so I changed the Library path to: C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\lib. I was then able to compile my program but when I clicked a button, none of the code ran!

I went back to check my syntax and everything was correct hence why I was able to compile my program (note: my code and program was left untouched for weeks). I then tried to re-install Delphi (2 times) expecting that the Library Path would fix, but it didn't.

After the failed attempts of trying to restore default settings I did some researched on stackoverflow but I could still not find the answer. Topics I've come across:

Delphi XE : Lost Library path

Delphi can't find System.dcu; what should the default path settings be?

I added the ShowMessage function to test if it worked and it did so I really have no clue what the problem is. However I am still suspecting that my Library Path is incorrect.

What do you guys think the problem could be?

• my code
• or my IDE library path

Note: current library path = C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\lib

Also, how can I fix this problem?

I guess the linked answer should solve you problem. If you need specific data for Delphi 2010, here is the registry file for 64-bit Windows (for 32-bit Windows the registry branch should be [HKEY_LOCAL_MACHINE\SOFTWARE\CodeGear\BDS\7.0\Library]):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\CodeGear\BDS\7.0\Library]
"Browsing Path"="$(BDS)\\SOURCE\\WIN32\\VCL;$(BDS)\\source\\Win32\\rtl\\common;$(BDS)\\SOURCE\\WIN32\\RTL\\SYS;$(BDS)\\source\\Win32\\rtl\\win;$(BDS)\\SOURCE\\WIN32\\WEBSNAP;$(BDS)\\source\\ToolsAPI;$(BDS)\\SOURCE\\WIN32\\IBX;$(BDS)\\source\\Win32\\Internet;$(BDS)\\SOURCE\\WIN32\\PROPERTY EDITORS;$(BDS)\\source\\Win32\\soap;$(BDS)\\SOURCE\\WIN32\\XML;$(BDS)\\source\\Win32\\db;$(BDS)\\source\\Indy\\Indy10\\Core;$(BDS)\\source\\Indy\\Indy10\\System;$(BDS)\\source\\Indy\\Indy10\\Protocols;$(BDS)\\source\\database;"

If plain import of the above registry file does not help:

1. Reboot and try again;
2. If the problem persists, delete Software\CodeGear\BDS\7.0 branches from both
   HKEY_CURRENT_USER\ and HKEY_LOCAL_MACHINE\ hives and reinstall Delphi;
3. Never run automatic installation procedure for unknown component packages on your working system.
