Some Windows games fail to install

[alkazar]

Installing the Windows versions of the following games fails:

• FTL
• Tyrian 2000
• Theme Park
• Flight of the Amazon Queen

and probably more.

Installing some other games works, such as:

• La-Mulana
• Reigns
• Akalabeth: World of Doom

Log output on failure:

Looks like some kind of an encoding issue perhaps?
