Error Code 2 Updating/Installing Java under Windows 8.1

Question

I haven't been able to update Java under 8.1 and, since uninstalling Java, I now can't install it. The problem is always the same...

I get a "Java install did not complete Error Code 2" message after Java has downloaded and gone through some process of installing and before it completes.

Googling, looking at the Java site, etc. has found no other references to this problem/error code and, of course, there is no way to contact them.

Answer 1

I had this error too. It was an easier solution than expected.

My last try was to install with another admin account. This worked for me.

My usual userprofil must have some regkeys or folderproblems (may be with folderredirection) why java was not able to install.

Regards.
