https://bugs.winehq.org/show_bug.cgi?id=57631 --- Comment #4 from RonSMeyer <nosoy1(a)charter.net> --- Running the same sequence below with version 9.20 and 10-rc6 I removed the long strings of terminal responses for brevity, which I can send if you want. I did not install MONO ie8 installed in both cases. I did not check the install ie8 updates box. I selected reboot later. The program I'm running "ThumbsPlus10" uses ie8 for http and also uses it for program help and other screens. I have been running this program in wine for almost 10 years. But, after Version 10, it fails immediately. I discovered the "uninstaller" fail when I tried to reinstall ThumbsPlus into a clean prefix and "uninstaller" (Add/Remove Programs) fails first. In the examples below, ThumbsPlus is not in the prefix at all. So what can I say. It worked with Version 9 and before, and now with Version 10, it doesn't. ron(a)RCS1:~$ wine --version wine-9.20 ron(a)RCS1:~$ WINEARCH=win32 WINEPREFIX=~/Pref920 winecfg ron(a)RCS1:~$ export WINEPREFIX=~/Pref920 ron(a)RCS1:~$ winetricks ie8 ron(a)RCS1:~$ wine uninstaller Add/Remove Programs starts. ron(a)RCS1:~$ wine --version wine-10.0-rc6 ron(a)RCS1:~$ WINEARCH=win32 WINEPREFIX=~/Pref10rc6 winecfg ron(a)RCS1:~$ export WINEPREFIX=~/Pref10rc6 ron(a)RCS1:~$ winetricks ie8 ron(a)RCS1:~$ wine uninstaller Immediate Fail wine: Call from 7BD50E18 to unimplemented function iertutil.dll.653, aborting -- Do not reply to this email, post in Bugzilla using the above URL to reply.
