How to do mixed installs form different distris:

Boxed version of HOI3-For the Motherland:
German Boxed version of HOI3-For the Motherland at Amazon
Also Semper Fi was available in Germany and Poland as boxed version.
Because of different names(localisation files) for censorship , the initial german boxed version of HOI3 had a different checksum.
But installing a patch may solve that.
The problems with Steam is, that they just do not set some Reg entries, because they handle software through their own software installer. So you have not the Reg entry that the patch is asking for...
Now Paradox could make sure that their patch installer is checking all the possible ways their partners do the install, or their partners just add this key to the Registry. And now you could maybe imagine what is going on behind the scenes. As that means additional costs and maybe some does not want to spend it.
If you don't get the patch in time through your Ditributor blame him!
IMHO thats the way to go. As the Developer P has done everything right in a senseable way to install the software. Only the Distributor that have
for their business modell different ways to distribute the software have problems..
