Borland C++ Builder 6: Missing component palette, Environment variables wrong?

[gsap]

I need to modify some legacy applications built in Borland Builder C++
6 personal.
I'm a beginner with Borland builder.

I can build and run the application but I am getting errors with the
forms when I load the project.

I'm getting errors similar to this: "Error Reading Form: Class
TBitBtn not found"

I'm also missing the component palette in the IDE.

What is the correct settings for environment variables?
Right now at the OS level I have these in the path:
E:\Program Files\Borland\CBuilder6\Bin
E:\Program Files\Borland\CBuilder6\Projects\Bpl
and
Is there a registry setting problem?

Solution from "YH" found (in this forum)
From the other thread:

-------------------------------------------------------------------------------------------------
First, go to the \Bin directory of your BCB6 install, and run the
utility
called BCB6RegClean.exe that you find there. Doing so will wipe
existing
BCB6 entries from your Registry. A side effect of this is that you
will
lose any user settings and have to re-register the product. This
will
ensure that you have a clean slate to start with.


Then, afterwards, run the Repair install again. That will write the
Registry keys back. Let me know if that helps.


The reason I recommend this is because the problem is in your
Registry. The
component package registration, pathes, etc., are all stored there.
So,
you're missing some Registry keys, and we're trying to use the
installer to
write them back.
