Heureka!!! At least partial success!
I couldn't beat the mentioned OLE error. Extracting the .exe was not possible due to an all too new version of the installer, even not under a native Windows. So after not being able to load Aslain's, I tried other modpacks:
1. Diclovit's Modpack can be installed without errors, but the game keeps crashing with this modpack installed. 30 secs after starting a new round, the game closes, right together with PlayOnLinux and Wine. My programming knowledge is weak, so I didn't find out where it crashes. And I forgot to debug it before ultimately deleting it... *shame*
2. On the other hand, it will not be necessary, 'cause: Webium's Modpack finally works very fine under PlayOnLinux. It shows indeed an OLE error too while installing. Funnily it's exactly the same error message like Aslain's shows, just at another adress (110:93), and this installation continues without any further incident. Furthermore, I couldn't find a parameter what brings the game to a halt or let's it crash. Until now, all mods installed by the modpack are working very, very fine, even the included "Kriegstreiber" sounds. Astonishing! I didn't figure it to work with all the parameters!
It took me 3 days to figure this out; I don't even know anymore, how many times I restored the virtual drive from the POL vault in order to let's try this, let's try that...
There's just one thing now that makes me curious: Why is the EULA window always empty? It was like that with all the three modpacks, independent of any errors. How I told already, I'm not the guy who reads this things regularly, I'm just curious about it.
Have a nice day and good fights to the WoT gamers!
Edit: The game crashes too, but just once or twice a week. In fact, it's so rare, that I didn't manage yet to catch the error in the debugger... Guess, there are Windows users with more software incidents... ;) And even when I'm not able to find the error, I can live with that.
