If I was you, I WOULD NOT put it in the directory.
Simple fix I use is to download sparkiv as a .rar/zip file. Instead of pulling out the .exe file, click extract to and extract it to a folder. (if the extracting doesnt work then pull out all of the files in the zip and put it in a folder by itself. Then highlight all the items and right click. Then click like make .rar file or something like that.)
So now when you want to use spark, you can open up the original .zip file using winrar everytime and you wont get an error. Its what i have been doing for about 6.5 months:D
