NT6.5 won't load after installing NT7

[h1000]

Hello,

I've been using NT6.5 on an old laptop and finally decided to install NT7 alongside my existing NT6.5 installation.

NT7 installed fine using the NinjaTrader.Install.msi installer package, but now NT6.5 doesn't run. The desktop shortcut does nothing – no splash screen appears and the program doesn't start. Even clicking on the .exe file (C:\Program Files\Ninja Trader 6.5\bin\Ninja Trader.exe) results in no action.

I uninstalled NT7 but NT6.5 still won't run.

Unfortunately, I can't reinstall NT6.5 because the laptop is behind a firewall with no internet access (I use Ninja on the laptop only for backtesting so this has never been an issue before).

Does anyone have an idea how to fix this?

Is there an offline installer file available for NT6.5?

OS Details:
Windows Vista SP1

NT Details:
6.5.1000.5
