I don't know that one. Possible solution is to delete the entire block of code around where it reports the error and retype it. Not just copy and paste, but retype. Copy it somewhere safe first, delete the original, see if it compiles, then you can determine whether the problem was in the block of code you removed. If there is still a problem, paste it back in and start scratching your head. If there is not a problem then retype your code. Sometimes Delphi seems to corrupt the source files somehow.

Also try deleting *.~* (the backup files), dcu, exe, etc.

have you tried on another machine?
do you have an antivirus?
sometimes it happened to me too with D4, but it happened once a month. It was always a delphi problem.

if you can you should format and reinstall the OS on your originary machine, then install delphi and see is the problem comes back again.
If it persists, you can point to the video card ( any strange brand of video card?)

Oh dear, oh dear. Always back up your registry before making changes. I guess it is too late now unless you have a backup somewhere.

Listen to me:
your last chance is to format and reinstall OS
If you ruined your registry and you don't have a backup of it, then it's the only reasonable choiche...

yes, manually rebuild your registry... :-)

(if you have reinstalled your delphi as you told,and the problem comes back again, then I think that the problem is in another part of your system...)

Summary is basically:
- delete all .dcu files
- check you don't have old packages in your system (obsolete, incompatible, corrupt, etc)
- turn on the option to "compile with packages"
- rebuild project (not recompile, but build)

Instead of increasing the points, it's better to make a resume' of what you tried:

on your machine it fails to compile a project
you have tried to reinstall Delphi, but the problem perstist
on another machine you don't have the problem with the same project
you don't have an antivirus (get a free scan at www.antivirus.com)
you worked with register
you haven't reintalled windows.

please check all these statement and tell if they're all correct, and then we'll see.

Surprise!
turn on the original machine and go on project options of the original project and turn off "use runtime packages", then rebuild all, and it could work...

Using runtime packages decreases the size of your exe. If you are distrubuting five 500kb programs, as much as 350kb of *each* exe has the same code/data such that you get 1.4Mb of spurious data that you don't need. You then use runtime packages which cuts down on size, but you obviously have to distribute the BPLs (VCL70.bpl and so on).
