I have this error and I'm unable to upgrade my program. I try uninstall it, reinstall it. Nothing. During instalation message window want me to choose file NUPAABE.msi . I search everywhere on my disc, file by file. Nothing. Is it matter that few years ago when microsoft allow do download for free win 10 I did it then back again o win 8.1 and now file above is lost forever ??
