Purchasing Borland C++ Builder v6 Personal [closed]
Solution 1:
Is there any option to legally purchase BCPP Builder or whatever but register and keep using the old stuff?
Not directly, no. The old products are long dead. They are no longer sold or supported.
However, if you purchase the latest RAD Studio version, you can get licenses for old versions, including C++Builder 6. See the following page for more details:
