what happened to me:
1-I was using the krita second demo for version 2.9 and installed it (everything worked correctlley)
2-I uninstalled it
3-since it was a demo I decided to clean all Krita folders of my system to make a clean install with the older version.
4-I tryed next to install a lower version of Krita and it did not work, and checking now that I unable to install ANY version of krita.

Error:
ussually the error is a "unable to access" a folder or file he is creating. like a png, brush or dll. it is not a fixed error but it always happens on about the same location.

I really love Krita and not being able to use it is hard on me DX I might even consider formating my PC just because of this.

I am passing my anti-virus and my malware through my pc to see if I have something else bothering.

what should I do?
Is there a way to clean the system to make a fresh start for the installer? some way to make sure it does not have any hickups along the way.
So thank you

that's terrible! D: i have linux version, so i cant help you. I think you'd have better luck posting to the krita subforum, it has a subforum specifically for krita on windows. here's a link. good luck!

I think may have got a big dose of some internet nastyness, not sure what it was so I took the chance to and formatted my computer whole.

I am sorry to have bothered you guys since krita was the only program working ill at the time I thought I could have some corrupted file annoying the installation, but I used krita installer in safe mode and it worked perfectlley so it was surelly my windows to blame. I am just happy I can use krita again yey \o/

thank you for the support with this miss filed issue.
