I just installed ACT 6.0 from a packaged installation with Admin Studio 5.5. I could NOT uninstall it. Furthermore I could NOT uninstall any programs. The "Add & Remove Programs" window would not display anything. In fact none of the options in this window were accessible anymore.
I finally installed ACT 6.0 from the original media over the top of the packaged installation and I was finally able to get the uninstalls working again.
Now, I am at a loss on how to stop this from happening so I can deploy this package. The program seems to work fine other than what happened above.
Any Ideas?
