Delphi Crashes on installing Package

I have a package using Unit A and B.
Both uses some other Units. There are no Circular References. If I Compile the units in a program (no Package) everything is fine.
if I want to install the Package I get the Error
Access Violation at address xxx reading address 0000.

For Testing I removed all Code except the Uses Statement and the Crash occurs.
If I remove Uses A in Unit B everything is fine.
I tied Uses in Interface an in implementation part.
I Use Delphi 3.01.

What can be wrong?

Check if there is an Initialization section in the unit (in the uses) which causes the crash.

I had a similar problem a couple of months ago. My problem was called by a copy of the unit being stored somewhere else on disk. Once I deleted this copy, everything was fine.

So, check that you have one and only one copy of the unit you are using on disk or on the network in your search path. If you have, delete all instances except the one you are using.

it might be something like your trying to install a run time package, that will generate a Access Violation...Go to the requires tab and remove everthing in it click compile and see what it tells you it added and then see if one of them packages is causeing the problem...you may want to delete off the runtime packages that it requires and rebuild them (save them to a back up just in case :)

Check initialisation of all (implicit) included Units.
If your Programm works when ist is compiled normally and crashes if you install the Package, I think the initialisation of the Units depend on a order of loading.
When you compile the package, the units are loaded in a different order so the "second" initialisation is executed before the "first" one and causes the Crash.

Make sure that each initialisation works in any loading order of the Units.

I created a global TStriglist in one initialisation and accessed from another.
