can't install M&B (nsis error, but on a bought cd?)

[UmenMan]

Since today I've a problem by installing M&B. I know, others seems to have the same problem, but I bought the game in a pc-store about 4 weeks ago.
After the installer is verifying, i get the message below. I installed and played it yet. After I uninstalled it, i wasn't able to install it again.

It's no problem anymore, I've found a way to install.
