Post the errors and we'll see what we can do.

 

[gazlappy]

the errors are no longer the problem i have decided to go to Delphi 6 and the errors have now gone.

i think i had better do this one step at a time,


OK what i need to to, as the program was created 10yrs ago it is becoming a problem with windows becoming out dated how do go get it to run compatible with windows 7 ???? (the built in windows compatibility does not work)

p.s thanks for replying also please bear with me as i said complete beginner

If you can compile with D6 it should run under Win7 just fine.

As I understand from several posts by Daddy concerning Win7, it depends on where you run the app from, if compiled for 32-bit.

I think the main problems with 7 (and Vista) concerns registry access.
If your program attemts to modify anything in HK_LOCAL_MACHINE (HKLM) then you will get an error (at least with a normal user account).
There are ways round this but probobly better to change it to use HK_CURENT_USER (HKCU). I would say this is better practise anyway.

I was hoping Daddy would jump in as I don't use vista or win7. I think it needs to NOT be under directory \Program Files\ but not sure...

I installed Delphi 7 Pro on a Windows 7 Pro machine in a folder off the root (C:\Delphi7) and have not experienced any problems.

I think everything important already has been said. In fact these rules can be applied to a much broader scope.

- don't think of installing under the default program files folder if your program wants to write in it's installation folder.
- take folder and registry virtualisation into account (this was already the case with windows Vista)
there are many resources on the net, I include one of them:

This mess (that came with vista) is a direct consequence from the fact that many developers didn't follow microsoft design guidelines in the 2000/XP era.
Being a developer you are responsible to make applications that behave correctly on top of the OS they are running.

Here are the design guidelines for W7, It is a vast resource how to make W7 consistent apps:
