We have a Delphi 5 application, that is built without runtime packages, dlls or external resources (i.e. a single executable). when we install it on a clients PC we get the following error messages:

Class TListView not found

or

Class TImage not found

We have installed it on dozens of PCs before without incident, but this latest install is problematic.

The target PC is a fresh install of Windows XP (Service pack 3) with no other software installed.

It does not complain about all of the classes however just one or two. for example TPanel/ TForm/ TEdit are all OK.

Can anyone think what is causing this?

EDIT

The exe on the new PC is on 30 or so other PCs that I know of, ranging from windows XP Sp1,2,3, Windows Vista and Windows embedded. both old and new PCs were installed with an old version and then updated with the newest version. The only difference is that the version jump was higher for the latest install.

  1. Re0sless,

    I suggest you open and close every form of your application and do a fresh build after that. If memory serves me well, that was the solution when we encountered similar problems.

    You might also take a look at DFM Check to open and close all your dfm’s automatically and at CnPack to help you clean your uses clause.

    Regards,
    Lieven
