Tune up on an additional computer

Desktop running Windows Vista Business SP2.
AMD Athlon 64x2 Dual Core processor 3600+ 1.9gHz.
4gB RAM. 64 bit Operating system.
NVIDIA Geoforce 6100 nForce 405.

No other tune up program installed.

Many thanks.

Hello Val,

We are sorry to know this.
May I know in which device did you try to install AVG TuneUp?
Is there any other conflicting TuneUp program installed on that device?
Please keep us updated.
Thank you.

Tune up worked brilliantly on 2 of my computers. On the third, the setup would not install and I got the message:
"The procedure entry point K32GetMappedFileNameW could not be located in the dynamic link library KERNEL32.DLL."

Any help please? Thank you.

Thank you for clarifying, Val.
We're afraid as AVG TuneUp is compatible with : 
Windows 10 except Mobile and IoT Core Edition (32 or 64-bit); Windows 8/8.1 except RT and Starter Edition (32 or 64-bit); Windows 7 SP1 or later, any Edition (32 or 64-bit).
It can't be used on Windows Vista. You may need to upgrade to operating system, in order to install AVG TuneUp.
Thank you for your understanding in advance!
