I’m installing SP1 for SQL Server 2008 64-bit and I kept getting an error message: “Invoke or BeginInvoke cannot be called on a control until the window handle has been created.”
The workaround is find the GUID temp folder where the setup files are extracted and before hitting the “OK” on the error message, copy those files out to another location. Hitting the OK button will make the GUID folder go away, and at that point you can run setup from your folder.
I am not sure if this is happening because i’m running the setup from RDP or what, but it got pretty annoying after 4 tries.
