Hi
I installed and re-installed Laz 1.10.
I can't get rid of this error
"interfaces.pp(29,3) Fatal: can not find InterfaceBase used by
Interfaces, ppu
incompatible=C:\lazarus\lcl\units\i386-win32\interfacebase.ppu,
paquete LCLBase"
What does that mean?
Should it be looking for interfacebase.ppu in another location?
If so which one?
And how do I set the path correctly?
Thanks

PPU's from different FPC versions _OR_ from different targets (e.g.
win32 vs win64 or 32-bit vs 64-bit Linux) are incompatible.

So somehow you mixed up versions.  Sometimes using -va will help, but
for beginners, it is better to be prudent while setting up/installing
FPC. Not messing it up is easier than resolving it when messed up.

Thanks.
but i did not use any -va because I simply executed the lazarus
installation EXE.
I am not exaclty a beginner, I have been using Lazarus a few years on
and off, but I always used the installation EXE, i do not know
how to install otherwise.
And these sudden disruptions of the IDE happened a few times.
Anyway, could you tell me how to remove *ANY* file or registry entry (
I mean really any) that could store a previous configuration so i can
really really re-install Lazarus fresh? I would appreciate it.

As far as I know Lazarus doesn't use the Windows-registry at all. It
does use a default configuration directory. You indicated in the other
thread you had installed the new Lazarus to another directory. If the
old directory still exists (and also your config-directory) that could
be the cause of your problems.

Standard installation Lazarus files: C:\Lazarus
Standard installation Lazarus config files: %LOCALAPPDATA%\Lazarus
(I think)

(you could type %LOCALAPPDATA% in your explorer-window)

When you install Lazarus you have a choice to install as a secondary
installation. If you do it asks you for a configuration directory. In
that case it doesn't take %LOCALAPPDATA%\Lazarus but you can provide a
complete other directory. (I usually do this when using trunk as
C:\Dev\config where Lazarus goes in C:\Dev\Lazarus and FPC goes in
C:\Dev\FPC)

You could use fpcup to install the latest trunk version.

But... You mention Lazarus 1.10 ???? And are also saying C:\xxxx so
you are on Windows. Why are you using such an old version. The
standard installation at this moment is Lazarus 1.4.2 with FPC 2.6.4.
I think you even need to dig very deep to download Laz1.10.

sorry Rvk
I am getting blind duew the numerous re-installation.
No, I do use Laz 1.4.2.
I will keep you posted.
I removed any resemblance of "lazarus" form my PC, (files, folders,
etc), even removed the renamed directory that it was previously
installed.
Trying to install now.
