@burnout426 thank you friend i figured out that its a permissions problem and i fixed it using Permissions Time Machine Lite, it helped me to reset permissions to default for the Appdata folder and now extensions install fine ^^
Thank you all for the great support

I did everything from reinstalling, to resetting my windows Permissions to recreating a new profile
but i still can't install Extensions, it happens in Google chrome too and i found no answer or fix for it
it didn't happen before
can anyone help ? i don't want to reinstall my windows, i use Windows 7, not a fan of Win10
Opera and chrome used to work fine but now i can't install any extension because it says Could not install package: 'ERROR_REMOVING_OLD_IMAGE_FILE'
