Hello everybody, I installed Rad Studio Athens ( with some graphic 3rd parties) and now I am trying to open some projects that I have done in Alexandria ( Rad Studio11). Unfortunatelly I am not succesfull - (access violation at address 00876830 in module "Project1.exe" (offset 6830). Read of address 000000000.) I am working with C++ Builder and before I had no problems with migrating projects from previous versions of Rad Studio. Any advice that could help me running older projects?

I am sending the CPU window after debugging pointing to ntdll.dll

I tried to migrate to Rad Studio 12 Athens another older project from Rad Studio 11. I run it with debugger and it shows: 1) still within c++ builder window: 2) then continues to pop up c++ builder window with: 3) After I close all pop up windows it shows in application window another series of alerts: Access violation remains in first case in module rtl290.bpl and then in module Project1.exe I could not monitor anything with debugger, because closing the alerts led me to the application with another series of alerts.... Hmmm, thx for any advice

I tried with debugging, it looks like there is problem with for loop: for (int j=0; j<c; j++) The initial value of j after running with debugging is 12 (j=12, see the image) , although it should start the loop with value j=0. There seems to be another problem with c, which shows no value at all. j and c are defined as follows: TForm1 *Form1; const int c=9; TBitmapLayer* pLayer[c]; int i,j=0; int r; bool slip[c]={ false }; bool bing[c]={ false }; bool bong[c]={ false }; int alpha[c]={ 0 }; ..... If I replace in the loop c with cc ( which is defined solely as int (int cc=9 ; ), not as const int (const int c=9;), then the value of cc shows as expected, that is 9. I might be totally wrong, never worked with a debugger before. I attached the image of debugging window below. Is it possible that some kind of "compile settings", which are different from previous version of RAD Studio make this problem? Thanks for any advice.

I am not used to work with debugger or stack of called methods. I will try it anyway. Is it of any help if ( in case of not able to interpret debugger window...) I make a screenshot of debugger window and post it?
