I’m running Ubuntu 10.04 LTS. After installing Wine-1.2.2 (type wine –version to check) via sudo apt-get install wine within a CLI terminal, I tried to install a *.msi file via the following syntax:

~$ wine install.msi

Unfortunately, this produced the following error message to be displayed:

~$ wine: Bad EXE format for Z:homeziffstarinstall.msi

The solution, to install *.msi files in Wine, is to use the msiexec program. The appropriate syntax to launch a *.msi file is as follows:

~$ wine msiexec /i install.msi
~$ wine start install.msi
