Hi Gabe,
This may prove to be a duplicate as I've been having trouble accessing the Forum.
Thanks for the follow up. No problem with the delay as I have also been delayed in getting back to this problem.
The problem still remains, as thus:
I right click on installation package (Affinity-Publisher-Beta-1.7.0.305) and run as administrator.
UAC asks to confirm instruction (Yes)
The Update window appears, click on ‘Update’
The window says ‘preparing’, then after a few seconds ‘Setup failed’. (Click ‘Close’)
However, having investigated the set up logs as advised by Walt Farrell, I believe the problem may be involved with establishing the installation path, either my desired or the default. I'm investigating this in the next few hors and am hoping to respond with a clearer answer afterwards.
Thanks again
Ian
