WC3 TFT not work after update

Up until version 1.31.1 of Warcraft III: The Frozen Throne worked without problems. After installing the latest update in the folder C:\Games\Warcraft III\x86 disappeared all files *.exe. I have Windows 7 32 bit installed. How can I run the latest version of Warcraft III: The Frozen Throne on this operating system ?
Please do not give advice: “Reinstall the Windows; buy a new computer.”

Alexey, a 64-bit operating system is required for Warcraft III if you are experiencing any issues with installing the game now. Here’s the system requirements for Classic and Reforged after the 1.32 patch. If you have any feedback, please provide this over in the #general-discussion so that our team and community managers can take your feedback into consideration.

I’m not able to access the Frozen throne either. I have windows 10 64 bit. I just completed the campaign for reign of chaos and the other 3 chapters are locked. and dont have access to rexxar campaign either
