Many have wonder why they receive an error : "InstallPath" thingy.

I'm sure you copied your version of Warcraft III from somewhere and pasted it in your PC.

Well, you can't update your Warcraft III if you did that simply because your PC doesn't recognize the path which is why the 'InstallPath' error occur. You'll need to tweak something before you're able to do so.

Step 1 : Download the Patch
When you click this link, you'll get FILE NOT FOUND. Don't worry, just click it at the URL and press ENTER again and wait till a download message pops out. it should take less than 20minutes to finish downloading it.

Step 2 :
If you're using Windows Vista or Windows 7, type "run" on the search bar and select the first result. If you're using XP, just find the ''Run".

Step 3 : Type "regedit" as shown in the Figure below


Step 4 :
Registry Editor will open. Follow the following commands in order and you'll be able to find them:

• Double click on HKEY_CURRENT_USER.
• Double click on Software
• Double click on Blizzard Entertainment
• Double click on Warcraft III

On the right panel , you'll see only (Default) string.
Right click on any empty space on the right panel and You'll see New then select Binary Value.
Rename it to InstallPath

*IMPORTANT*

• Dont close your Registry Editor!
• The next thing you need to do is to copy the directory to your Warcraft III folder.

After copying, go back to Registry Editor and double click InstallPath, paste it at the empty space.

In the registry editor, under the Warcraft III, you'll see String folder. Double click it and do the same thing there.

Close it and voila, you're done with tweaking the directory to install.

Should look something like this in both Warcraft III and String :

Step 5: Run your updater and go into Frozen Throne.exe to see if it's version 1.2.4.xx.xxx!

Precaution

• Just in case if it doesn't work, try deleting the folder and replace with the one you have backed up.
• Delete the InstallPath in both Warcraft III and String (in Registry Editor)
• Do not delete the backup version of 1.2.1x just in case you want to play with your friends that didn't update their Warcraft III.
• The 1.24b version doesn't allow you to play dotA 6.61c and below. Not so sure about other TD maps.

Have Fun Folks! I hope this help some
