Works fine here, but then again I also have the smoke indicator selected, which sets navigator to true properly.
So there must be an issue with just those 2 together.
Try rebooting.
Check if your antivirus software is messing with the installer.
Check permissions for the folder in the error message.
Not sure what else to mention.
Stating the obvious here
Of course the 9.19.1 version isn't backwards compatible with older World of Tanks installations.
Use your 9.19.0 modpack installer. Or wait until ASIA gets updated.
Ask WG to stop updating both games within a short timespan then...
And servers usually tend to have issues anyways.... with all the people trying to get WoT modpack instantly... everyone hammers the refresh button, spam clicks links, because "Oh no, they're slow, maybe it'll help if I open the link 100 times"
I take it you posted on my profile instead of replying here? Anyways, you downloaded the wrong modpack, otherwise it wouldn't give you that error...
Read the download page carefully, since there's links to TWO different versions of World of Tanks. You want the first one. It clearly shows the version numbers on there.
You'll need to just wait....
WoT update and WoWs update on the same days = Server is going to break, from the many many thousands that wants to download right away.
