There is a new bugfix release in the 2.0.x line: ejabberd 2.0.2.
In the last three months several bugs were found and fixed. As mentioned in the release notes, the main changes are:
Anti-abuse feature: client blacklist support by IP. Guide: new section Securing ejabberd; improved usability. LDAP filter optimisation: ability to filter user in ejabberd and not LDAP. MUC improvements: room options to restrict visitors; broadcast reasons. Privacy rules: fix MySQL storage. Pub/Sub and PEP: many improvements in implementation and protocol compliance. Proxy65: send valid SOCKS5 reply (removed support for Psi < 0.10). Web server embedded: better support for HTTPS. Binary installers: SMP on Windows; don't remove config when uninstalling.
The source package and binary installers are in the ejabberd ProcessOne download page.
If you are using ejabberd 2.0.0 or 2.0.1, you surely want to update to this new 2.0.2.

Does installation finish? Then start ejabberd and check window
Maybe PostInstallation finds a problem, but the whole installation can finish.
In that case, try to start ejabberd with the shortcut and check the MSDOS window: does it show an error message about 'need to install some package from Microsoft...'?
