i suppose that's a steam installation?
have you tried downloading installer from site and installing?
p.s. you've got 6.2 GB of processes - that's... too much XD i mean it's ok because you got 32 GB of ram, but do you really need all that?
here's some i've noticed that could be removed (if you're not using them (i'll compare to mine)):
- akamai session
- chrome cleanup ?
- display fusion (why are you using this on win10?)
- dropbox update
- geforce experience
- intel management services - they are all useless (as much as i've tried and looked they didn't do much, they just get in the way)
- itunes / ipod helper (unless you have iSomething)
- java updater
- msi afterburner (i suppose you're overclocking )
- nvidia driver + network services
- bandwidth meter?
- sierra service?
- skype updates
now i suppose you've got this all installed and you're using most of it, but if you're not just uninstall all unneeded programs, most of them that "offer" performance and what not actually make your system work worse then it actually can and just slow it down. now you could run a spyware / virus check aswell as you might get suprised by some random unexpected thing.
i know what your answer probably will be: "but i need all these, i'm a programmer / designer / etc.." and that's fine if you work with it.
i've got my developer stuff on my pc installed (lots of it) but still i have less processes then you. (and i've got mercurial, visual studio, sqlserver, photoshop, loads of other tools, java, flash, etc.. ) they all have their processes but i've terminated them all, since i prefer manual work mostly. (most secure and fastest in execution).
p.s. also check your startup programs there might be some wierd things too. disable unneeded.
also someone mentioned ccleaner registry cleaning. try this:
uninstall c2,nwjs, clean appdata for c2, and run ccleaner, but beforehand install ccenhancer. (make sure you tick everything (except maybe browser history / session / passwords, and the things that pop up a window) and clean your drive aswelll. then run cc registry clean.
cc registry clean is pretty shallow, so i'd recommend you install wise registry cleaner. make sure in options you select "deep" cleaning and select "back up registy before cleaning", i think it's on by default. clean registry with this tool. you can also compress it with defrag for higher performance (it will restart your pc).
then try installing stable and check if it works.
if nothing helped sofar - it might be that your UAC (if you have it ON) is causing problems when running app.
also - open event viewer and check application logs. if there are yellow/red logs, try finding one with construct2.exe and details about the error. paste here.
windows shouldn't be a problem, i've been updating from 10240 to 10586 + all the new updates - and everything works ok.
