Have you tried rebooting?
I ran across an issue on Windows Server 2008 R2 but also found the issue to happen on Windows 7 installations.
Apparently this will be fixed in the R2 releases of SQL but since those aren’t available yet for the enterprise and similar versions, there’s a pretty simple fix. I found an article that references a few fixes that I’ll link to here in case the fix that I have doesn’t work.
The error states that “Invoke or BeginInvoke cannot be called on a control until the window handle has been created.”
I’ve done many installs and this is the first time I’ve seen it. This is going to sound like a joke, but the way I ‘fixed’ it was simply to reboot the server. That’s right, try to reboot it and run the installer again, before you try any of the other fixes. It worked like a charm for me. I’ll post a link to the article that I spoke of earlier, and if you come up with an alternate or had to do something special, please leave a comment with your fix.
Thanks and hope this helps. ‘Simple’ helped me out this time around. Wish a reboot fixed everything. 😉
