I go to add remove programs. 1-under java 6 update 24 it has no remove button. 2-under java 6 update 15 it says remove but when I click on this it says fatal error occured during installation, and does not delete it. 3-under java 7 update 7 it says remove but when I click on this it says the same thing, and does not delete it. 4- I also cannot access java tab in control panel, it says the system cannot find the file specified. 5- I have been wanting play minecraft and I cannot because of issues with java. when I click on minecraft.exe it says I need JRE 1.5.0, it takes me to the java website to download java 7 update 7, and when I click to download it says that a version is already on the computer and that it cannot complete download. 6- what do I do with this MBR.dat file on my desktop. I remember you said not to delete it. what to do?
