I have just bought the performance tune up software for my laptop running Windows 7 Home Premium. After I downloaded the .exe file I double clicked on it to try and install it but got an error message 0xe007f958.
There is no other info so not very user friendly! Any ideas anyone?
Thanks in anticipation…
