Can't run or uninstall MATLAB

158 views (last 30 days)
I have already contacted tech support on this but I figured I should post this here in case someone else has a problem later. Basically my computer runs 64-bit and I am trying to launch the R2018a version of MATLAB. It's already downloaded and installed but it won't launch due to java errors involving sun.awt.win32Fontmanager. Tech support recommended uninstalling and downloading a R2015a version or later but when I tried to uninstall its giving the error "Installer Error Exception Calling Main". This is where I'm at now with this. If any of you have a solution it'd be appreciated, I'm still waiting on a response from support.

If you are not able to uninstall it from Control Panel then, try to uninstall it from Program file of C drive. Go to the "C"--> Program files--> MATLAB (Browse your matlab file here), and delete the file from here. You can go inside also of R2018a and there will be a uninstall file you can do it from here also.

Yeah the Uninstall files gave the same issue but just straight up deleting worked without a hitch. No stray files that is.

maybe no stray files but lots of drek left in the (already bloated) windows registry.
