As some people noticed the addon would not install without having an orig. Patrizier 2 - CD (hmm, I have a CD... somewhere - but I can't find it :-().

Ok let's go:
0. I have an orig. Patrizier2 AddOn CD - If you don't have - the following may work or will fail (I don't know)
1. Install and let the install fail
2. Now there should be 2 files on drive C:
-- indigo.exe (the copyprot. check prog.)
-- tempsetup.exe (the setupprog.)
The size of tempsetup.exe _must_ be 442368 bytes.
3. open tempsetup.exe in your hexeditor
4. goto fileoffset 0000:1D97
5. change 0x74 to 0x75
6. save the file
7. open dospromt
8. run "C:\tempsetup.exe I_AM_SPAWNED"
