Good afternoon.
FYI, msiexec /a fails to create the correct folder structure under certain circumstances for administrative installation.
If the DirectoryTable of the .msi has entries which make use of the .: convention, msiexec /a "gets confused" and flattens the folder structure.
Anybody willing to contribute, and/or interested to try for themselves, please see
https://bugs.winehq.org/show_bug.cgi?id=58457
for an A-B test case Windows 10 vs Wine behaviour.
To run the test, no special know how is needed. Issue msiexec /a command in any plain Wine as described, and check the folder structure created - FileTree_Win10.txt contains the result delivered by Windows 10 for comparison.
The more test results and with different Wine versions, the better.
Thanks.
