    ^^ Strange! Why you guys are not having this folder, I have checked again, its there for me :) I insist you to recheck.

  • Thank you Kapil, I have been through quite a few procedures but then hit your site. How simple could this actually be……..brilliant.

    ^^ Glad we could help :)

  • Worked for me ! U can move the files to another folder as a backup, just in case… N.B. the hex error number was different in my case: “installer encountered an error: 0xc800003f3”
    Thanks alot
