https://bugs.winehq.org/show_bug.cgi?id=46466 --- Comment #3 from Reinhold <reinhold.hoffmann(a)hotmail.com> --- Thx for the immediate response. Please find a demo package in the zip file. At first please read the file "Readme_Demo_for_COMServer_bug_46466.txt" VERY IMPORTANT The COMServer.exe modifies the Registry as described in "Registry_Values_of_COMServer.txt" which can be removed executing the command as described in section 5. of the Readme file. I believe that the bug is that an 64-app cannot access 32-bit instances calling CreateInstance Could be that it is really not a big deal to fix that because the complete implementation of CoInitialize, CreateInstance, CoUninitialize works fine but just for one side (either 32-bit or 64-bit) but interworkng between these two worlds fails. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
