Highly Recommend!

So many times tech support is nothing more than a 'black' hole. Help is required, you submit the issue and it falls into the abyss. This is not the case with MaceCraft Software. Their software is solid, stable and their support staff is responsive and knowledgeable.

I don't give out A's often but MaceCraft Software deserves it. MaceCraft Software is an excellent choice.

The new JV16, with the system fixer is amazing!

This new version with the system fixer is amazing! Apparently, I was missing a C++ version, and JV16 found that it was missing, and clicking their link took me to the web page where I could download and then install the correct version.

I've used and owned their JV16 software for well over 10 years. In the past, they have been the only registry cleaner that I've had success with year after year, and I have tried others to compare and wound up with problems.

Using jv16 since virtually ever, there's little other to say about it apart from that it's a marvelous tool for keeping your system at peak.

Not much arguments for not using it.
