I just encountered the: “Error 997.Overlapped I/O operation is in progress.”
I had just attempted to download and install Microsoft SQL Server 2012 Express on my Windows 7 Professional (Service Pack 1); Processor: Intel® Core ™2 Duo CPU E7500 @ 2.93GHz; Installed memory (RAM): 4.00 GB; System type: 64-bit Operating System computer.
I went to a specific Microsoft web-site (which your message says that I cannot display)
and clicked on the big red “Download” button. Then check marked: ENU\x64\SQLEXPRWT_x64_ENU.exe
I had selected Run (and not Save) so I did not have an opportunity to select “Run as administrator”.
The download took a little over an hour and the installation began on its own. I took screen shots along the way. Ultimately I ended up with: “Error 997.Overlapped I/O operation is in progress.”
When the SQL Server Installation Center window appeared, I believe it paused there waiting for me to make a selection. I chose the first choice, “New SQL Server stand-alone installation…..”
I also have on this computer Microsoft SQL Server 2008 and Microsoft SQL Server 2008 R2 and I chose not to upgrade either.
Can you help me please with what to do next? Thank you.
