Hi,
After you perform “insert Integration Services setup disk”, the Integration Services setup file will run automatically. If it doesn’t run, you can located to X64 folder to run the setup.exe. I have several Windows Vista X64 VMs on Windows Server 2008 SP2 Hyper-V host and didn’t encounter your issue.
Please try to install another Windows Vista X64 VM to test whether you get the same issue.
In addition, I’d like to confirm whether you get the same issue with Windows Server 2008 SP2 X64 VM.
Best Regards,
Vincent Hu
