Hello folks,

just to shed some light about this issue because I got the original media from
someone ;-)

The game itself has no real copy-protection - just a simple CD check.

There is indeed a message stating "Please insert original ANNO 1602 CD!" when
starting a mission with the disk correctly mounted with drive letter assigned.

The game installer writes a registry key 'CDROM_DIR' which is derived from the
working directory where the installer executable was started from.

This is usually a path containing "Z:\\" because most people don't bother to
use 'wine <mapped-cdrom-drive>:\\setup.exe' (including me).

The game reads the registry key 'CDROM_DIR' and parses the drive letter part
out to do simple checks like:

* GetDriveTypeA() -> CDROM type
* GetDiskFreeSpaceA() -> compares with hard-coded size
(SectorsPerCluster*BytesPerSector*TotalNumberOfClusters)
* GetVolumeInformationA() -> disk serial

Well, you get the idea ;-)

Export of relevant part of registry:

--- snip ---
[HKEY_CURRENT_USER\Software\ANNO1602]
"CDROM_DIR"="Z:\\run\\media\\focht\\ANNO1602\\"
"INSTALL_DIR"="C:\\Program Files\\"
"INSTALL_SIZE"="MAX"
...
--- snip ---

You either fix the registry key manually or run the installer with real CDROM
driver letter path.

Resolving as 'invalid' because this not a bug/Wine problem ;-)

Regards
