Reg file for Windows 7

Question

I've been trying to update Far Cry 3, which I purchased via Steam, but I keep getting an error. I googled for a solution and I came upon several posts on different forums saying that updating the registry with 5 keys that the game is looking for before updating should fix the problem. So I created a reg file exactly as instructed, but it does not seem to work. I'm getting this error: "the specified file is not a registry script. You can only import binary registry files from within the registry editor."

Here's the content of the reg file. Any help will be much appreciated.

"[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ubisoft\Far Cry 3]
"InstallDir"="D:\\Games\\SteamLibrary\\SteamApps\\common\\Far Cry 3"
"SKU"="WW"

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ubisoft\Far Cry 3\GameUpdate]
"InstallDir"="D:\\Games\\SteamLibrary\\SteamApps\\common\\Far Cry 3"
"info"="ca32d7a363334a55b66633237b0335b7"

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{E3B9C5A9-BD7A-4B56-B754-FAEA7DD6FA88}]
"DisplayVersion"="1.01"

First of all, this is not how a registry file is made. (Taken from here)
First, open your .reg file with Notepad (or your favorite text editor) and put

Windows Registry Editor Version 5.00

as the first line. Then you can add the keys:

"[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ubisoft\Far Cry 3] "InstallDir"="D:\Games\SteamLibrary\SteamApps\common\Far Cry 3" "SKU"="WW"

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ubisoft\Far Cry 3\GameUpdate] "InstallDir"="D:\Games\SteamLibrary\SteamApps\common\Far Cry 3" "info"="ca32d7a363334a55b66633237b0335b7"

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{E3B9C5A9-BD7A-4B56-B754-FAEA7DD6FA88}] "DisplayVersion"="1.01"

So in the end, the .reg file looks like this:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ubisoft\Far Cry 3] "InstallDir"="D:\Games\SteamLibrary\SteamApps\common\Far Cry 3" "SKU"="WW"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ubisoft\Far Cry 3\GameUpdate] "InstallDir"="D:\Games\SteamLibrary\SteamApps\common\Far Cry 3" "info"="ca32d7a363334a55b66633237b0335b7"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{E3B9C5A9-BD7A-4B56-B754-FAEA7DD6FA88}] "DisplayVersion"="1.01"
