i found a solution & i was able to install my Waterfox.

But it's from another forum. is it okay to post the link to that other forum here?

Yes please.

Ok, to solve this problem, you will need to download something from Microsoft called "Visual C++ 2010 SP1 Redistributable. If you are using 64 bit Waterfox, it will be the 64 bit version of Visual C++ 2010 SP1 that you need to download. If you are using 32 bit Waterfox, (if there is such a build) you will need to download the 32 bit version.

64 bit version here: http://www.microsoft.com/download/en/details.aspx?id=13523

32 bit version here: http://www.microsoft.com/download/en/details.aspx?id=8328

So, if you are using 64-bit and I presume you are, click the link to the 64 bit version, download it, and install it. You may need administrative privileges to install if you are installing on MS Windows Vista or MS Windows 7.

Johndogg, thanks a lot; the solution you provided works, and my application is working fine. Once again thanks so much for your help...
