Spark will not start

I am using Windows 7 64bit, and cannot get Spark to work. Spark 2.6 would not even complete the install, so I went back to 2.5.8 and install completed, but when I click the icon, it does nothing. Nothiing in the task manager, nothing in the notification area, just nothing. I have uninstalled Vipre with no change in the end result. I know 2.6 works on Win7 64bit, as I have it installed and running on my PC, it just wont run on my laptop (HP g62 i5, 8gb ram). I have tried what I know to try… Any ideas??

Anything in the error logs?

disable ClearType in Windows and try again please

Wow… go figure… that worked! Also solved a few other ‘minor’ issues I was having… Thanks!!!

a bit googling helped, the java gui seems to hate cleartype

Well, for once a wise thing from Java. I hate cleartype too
