In what way is 11.0 integration not un-installed? If it still shows up in Add/Remove programs, doesn't the remove option work there? The 11.0 download and license won't go away unless you delete them in Windows, but those shouldn't impede an attempt to re-install an old version.
Tim,
The Integration Module does not show separately in the Add/Remove Programs, as it was the case with previous versions. So, after you complete the uninstall procedure, the entry in the Add/Remove Programs list is removed. So you assume that everything was removed.
In my previous post, I said that the 9.1 Integration Module does not install, not the Compiler Modules. So in effect I ended up with the older version of the compiler and the newer integration.
Following Steve's instructions fixed my problem and I was able to remove the beta integration and install the old one.
Daniel.
