Am sorry for my previous mistake of saying 62 when of course I meant 32 bit.

installed avg free protection successfully. Then I  upgraded tune up to pro. Had trouble installing but got technical help and installed. Now I need to reinstall my free protection but get above error code. Have tried 3 times to install with same result.
My Tune Up is installed - it's the free avg that's not installed any more. Will the avg free and the Tune Up be installed when I reinstall the free avg.
​Please let me know why my pc info says I have 64 bit installed and the link you gave me says I have 62.
