The issue with the free Viscosity Registry Cleaner software is that it is not as useful as a paid one. The user cannot check on the status of the file right away. You can access the file at anytime to correct a problem. Another problem is that it uses free internet connections which could cause problems for other applications. You should only download this software if you want to clean out errors.
It is true that cleaning up the registry manually can be difficult and time consuming and you will have to spend hours trying to do it and still you will not get the results you wanted. But, I can assure you that the cost of the software is very low compared to the time it takes to fix the problem. As a matter of fact, there are many software that is available to eliminate all errors with a single click. You can easily clean up your computer without any issues.
One problem of Viscosity is that it does not support the Windows Operating System. A number of people who have used the program have found that the program works just fine with Windows XP, Vista and even Windows 7. However, it does not work with Macintosh. Therefore, you can not expect too much. If you really need the Windows version of the registry cleaner, I would suggest that you purchase the program. However, you can download Viscosity Cleaner for Mac and try it out before you buy it.
