Can't install about deadlock HOT 3 CLOSED

Does your system have enough RAM available?

It looks like Inno Setup is warning you that your computer does not have the required resources available to actually run the installer.

Odd behaviour indeed, although the current build is, unfortunately, quite old. It's possible that on some systems, the older Inno Setup build might not work correctly. Very hard to debug.

Newer versions of Inno Setup might not have this problem. Closing this issue though, since you've managed to resolve it!
