Persistant installation failure on XP


I have just upgraded my computer and tried to install F secure to the new hardware. I get the "Installation Faled" repeatedly. I have removed the only possible piece of software that might have been conflicting as it had a "malware detector" within it. I have gone through windows update until it shows that there are no updates in any categories. However, the installation still fails. Any suggestions?

    Just upgraded your computer and you have XP?! Guess you mean hardware...


    For XP you need Service Pack 3, so make sure you have that.


    Here are troubleshooting steps for a failed installation:

    Also note this:


    F-Secure cannot guarantee the best protection and performance for customers running Windows XP after April 8th, 2014. This is because malware can use vulnerabilities in the operating system that are no longer fixed by Microsoft.

    Hi, Mboy!


    Did NikK's post solve your problem?


    If NikK's post didnt solve the installations problem, please take a look below:


    What previous anti-virus programs have you had on the computer?

    You mentioned that you have removed conflicting softwares, which softwares was this?


    Make sure so that you dont have Microsoft family safe installed which also is a conflicting program.


    If it is a Lenovo computer It can also be Lenovo Rapidboot that is the conflict.


    After you have checked all this info and you maybe found something and removed it then run F-secure Uninstallationtool that you can find here.

    After you have run the Uninstallationtool try install again and see if it works.

    The uninstallation tool link does not work. Where can I find the tool? The only possible conflicting software was Advanced System Care by IObit which used to run perfectly well with F secure on my old hardware. This has been uninstalled. If the suggestion is that F Secure will nolonger run with XP even though it was running well after April 8th on my previous hardware that would seem rather strange.

    Make sure IOBit is fully removed. It's been known to cause problems and even to do more harm than good from what I've heard. The company is highly questionable:

    I down loaded the uninstallation tool and on trying to run it the result was:


    Runtime Error

    This application has requested the Runtime to terminate in an unusual way. Please contact the applications support staff for more information.


    So where do I go now?
