cannot uninstall razer software, cannot reinstall razer software etc.

I deleted most of my system files for razer, used the driver cleaner for razer, updated windows, updated my drivers for my gpu. and im running my it in admin but wont open up the installer, a razer err file shows up when i use the installer but nothing shows up. I cannot get it to work or do anything as i was on 3.0 but when i tried to install 4.0 it asked me to use admin and never actually updated even after a restart and it completing the update. I seriously dont know what on earth caused the software to be acting up so terribly but at this point i cant install or use the software. ive deleted it completely from my pc using control panel and ive looked in every nook and crany and deleted the razor folders and etc which i looked up online but i STILL cannot get it to open or even work in the slightest. I game ALOT and its quickly becoming a MASSIVE problem for me ive went through absolutely any and every way to get it up and working again but it just isnt working.
