What is the expected output? What do you see instead?
Well, I would hope that it would install, but instead I get "The program
_INS5176._MP has encountered a serious problem and needs to close. We are
sorry for the inconvenience.

What version of the product are you using? On what operating system?
1.1.30? Source downloaded via git two days ago (27 Sept 2009), compiled
with all features enabled and installed on top of 1.1.25 on Fedora 10. I
installed 1.1.25 originally via RPM from Fedora's updates-testing
repository, and I installed 1.1.30(?) over it in /usr/ instead of /usr/local/.

Please provide any additional information below.
Yes, I cleaned out the .wine directory first.
