Why does the installation freeze or give me an error message?
Windows users: Make sure that you are attempting the installation from an administrator account on the computer. Also, verify that your User Account Control has been enabled and then try the installation again.
Windows 7 and 8 users: Make sure that you have Service Pack 1 installed on your PC. Then, restart your computer and try installing wtfast again.
Windows 8.1 users: Make sure you have installed the Windows 8.1 update. Then, restart your computer and try installing again.
Solution 2: Empty the contents of the TEMP folder.
Whenever tasks are completed or a program closes, files are stored in the TEMP folder. If many files have accumulated in the folder, you may receive errors that prevent the installation from completing.
To delete the files in the TEMP folder:
1. Open the TEMP folder inside the Windows folder on the C: drive (C:\Windows\Temp).
2. From the Edit menu, choose Select All.
3. From the File menu, choose Delete.
4. When asked if you are sure you want to delete these items, click Yes.
5. Once these steps are complete, close any open windows and restart the computer. Once the computer has restarted, try the installation again.
Note: If you receive an error that a file or folder can not be deleted because it is in use, skip the file and continue deleting the rest of the contents. Once you are finished clearing the rest of the contents, restart Windows and try these steps again before you open any other programs.

Your computer needs around 100 MB free hard disk space before you can install. Please ensure that you have enough space to install the player. You can make some space by emptying the Recycle bin on your computer desktop and deleting redundant files.

Note: When installing the application, you can restart Windows in Safe Mode and try the installation again. For information on restarting in Safe Mode, consult your Windows help files.
