In one of the above reply images, the Task Manager shows
that EL version is running in 64bit. However, having two or more instances of EL on the same system(s) could be whats causing an issue with a configuration file or maybe Java. If this is whats happening, then you can try to track down the issue or, uninstall all EL's from the system and reinstall(the easier/quicker way). From your PC hardware specifications, you should only need to run a single instance of EL on the fastest PC(imho).

If there isn't anything being saved in any of the main EL installation folder(s), then you can just uninstall/reinstall EL. EL should recognize the uninstall and not show up in the systems "Currently installed programs" list anymore.

Any other files/lotto's in folders can be Copy/Paste to another location if needed. Usually its best to backup to a separate storage device(external drive, USB, DVD etc.) just in case. There shouldn't be any loss of lotto data,...but you may have to re-download or reinitialize some plug-ins before they are recognized again by the new install.
You can create any folder you want on the system to install EL. Its just that when I saw "C:\Program Files (x86)" as the install folder in the other topic, I thought maybe a config file might be overwriting another, or Java 32bit causing EL to default back to 1GB(etc.). If you have only seen 1GB usage for EL up until now, then your in for a surprise for improvements.
Let me know if you need any more info.
