Since you are using SP2 which is a very old operating system we recommend you upgrade to Windows XP SP3. You would be using the online installers (downloaded from get.adobe.com/flashplayer) and that is signed with SHA256 signing certificate which is not supported by SP2.
Recommend you to run the uninstaller and then use the offline installers available in Still having problems section on Installation problems | Flash Player | Windows 7 and earlier page. This should resolve your problem. If you still see issues let us know about the same.
You're original post is quite confusing. You state that when you try to install Flash Player installation stops after selecting the update option, but then you state "On page www.adobe.com/software/flash/about/ it says that v22,0,0,209 is installed" What browser are you using when you go to the www.adobe.com/software/flash/about page?
A better page to check the version is https://helpx.adobe.com/flash-player.html. Clicking the Check Now button returns the OS, Browser, and Flash Player version (if installed). This is more useful information to us than just the version number provided in the about page.
Thank you for your answers, i know SP2 is quite old but all my configuration was working perfectly untill now so i'm kind of annoyed if i can't use flash anymore on my system, and it seems like i can't really uninstall the adobe files that are on my computer right now.
I say my installation stops cause i see the bar moving and then the installation windows brutally stops and i can't access any flash, as for the link you gave me asks me for a plugin to view the page, but for sure some files are installed as the first link says that.
Please tell me how i can manually remove all the files from the latest version on my computer and give me a link to directly download the full installation package for the previous version
