The DB Pro that I use now is a montage between the Dark Basic Pro (2005 CD) and the new compilers to the previous one.
The folder in which you are installed is:
C: / Program Files / The Game Creators / Dark Basic Professional
Attached image with a view of the files and folders it contains.
Since I am not sure how to install Dark BASIC Pro,
this time I copied and pasted a previously working version made up of several compilers,
maybe made up of the 2005 version (CD) plus the current compiler plus the DBPro9Ex version .
The subsequent addition overlapping the DBPro9Ex version,
was because the combination of only Dark BASIC Professional 2005 (CD) plus Compiler (New),
asks for Key, but Key can not get to my PC because that option is expired.
So this fact does not allow me to use my purchased version of Dark BASIC Professional (2005-CD)
Dark BASIC Professional 2005 (CD) + Compiler (new) compiler does not work.

DB Pro compiler (new) I can not instantiate nor it works overlapping its folders and files on Dark BASIC Professional 2005 (CD),
it gives me error that says it does not find the compiler.
It gives me the same errors as user as Administrator.
A month ago I installed the mfc100.dll library,
in the Windows / System 32 folder, with the program "DLL-Files"
Before that I say of Dll, I had installed Windows 10.
At the beginning of moving from Windows 7 to Windows 10 I worked fine
DB Pro, but in two months it stopped working and I did not find any
Fix it, so I had to remove windows 10 from my computer and go to install again my Windows 7.
But I see that the problems are the same ...
I have only programmed in BASIC languages, before DBPro in QBasic7, since Microsoft left QBASIC,
as it usually does with everything ...
I am not a professional programmer, I never did programming course, many years ago one of my brothers let me type his PC,
I saw that the screen showed the word "READER" and it was then that I started to program directly and saw that
I was getting enough Well, in 2001 I was able to buy a laptop and since then I have been programming and in various programming forums,
until I left the forum Dark BASIC-Es where I helped to create codes.
Subsequently, because of the relationship, I stopped programming from 2009 to 2016.
The first serious error, a starting from which the other mistakes were this -> "MouY variable does not exist in the program" ,
giving the reference of the Line where the error was figured, so that there was declared the variable without me
I leave Continue Programming my program for more than three months, change the name of the pen variable by other names
I kept pointing out as the error variable...
I have another data to contribute, when I compile, this warning appears ...
That says something like that would have duplicated several DLLs, I attached that message in this post.
NOTE:
I think it's good to update DBPro and take it to the max,
but apart from that, it would not be a bad idea to create something to be able to use the (CD) purchased from Dark BASIC Professional,
with that at least I could continue programming and improving my programs in this language wonderful.
The version I have bought on CD, I think it is the 1.9 of Dark BASIC Professional,
I bought two CDs, one gift to one of my brothers.
I also bought Dark BASIC 1.3 twice, but these without CD,
by downloading through the selling page of the product.
I also bought all the additions that had to implement the DB Pro,
but these were lost over time ...
The Dark BASIC Professional CD shown in the photo is the second copy I bought and is dated 2005.
I do not know if I am explaining myself well in English since I do not know English,
I only know Spanish, but I try to look good using Google Translator. SORRY...
